When do l4d2 mutations change

Chances are, however, that are not-as-easy ways to play mutations. Often, you'll be able to regenerate the effect with existing cvars -- usually cheating-protected ones, however. For example last week's "dev pick servers" for QL was slow motion servers, aka timescale 0. But in the last weeks it happened that Valve decided to repeat some successful mutations, like Chainsaw Massacre , for example.

It could happen also Valve decides that some mutations will become "always-playable" like they did with Realism Versus. Sign up to join this community.

Official mutations on left 4 dead 2 Ask Question. Asked 11 years, 4 months ago.

If someone has a Molotov however, they can attempt to set the Boomer on fire and let the flames kill the Boomer. On the other hand, if the Survivors are moving quick, they may opt to leave the Boomer alive as it takes up a Special Infected 'spawn slot', meaning a more dangerous Special Infected such as the Smoker or Charger may not be around.

Survivor Bots are hesitant to attack Boomers due to their coding working against them attack the Boomer only if outside the explosion radius. They will only shove the Boomer away from them if it approaches them. Players will have to step up and kill the Boomers themselves and deal with being splashed if they do not want the Boomers to paw the Survivor Bots to death. On the other hand, Survivor Bots do not care about being covered in bile and can still attack with accuracy even if blinded against other Special Infected.

Witches have a large advantage in this mode, as the Katana is not able to cr0wn them. Human players will have to either time their swipes to all hit at the same time in order to kill the Witch before she retaliates against the first person to hit her.

A more easier choice is to simply run by her and avoid her altogether. However, their Katana AI which forces them to run into melee combat will force them to run right up to the Witch in question, and wait for her to get angry enough, upon which, they will then attempt to attack, but by then, it may be too late for one of the Survivor Bots who has just been incapacitated or killed by the Witch.

Players will have to kill the Witch themselves somehow if they want to keep Survivor Bots on their feet. On the other hand, it may be safer to sacrifice one Survivor Bot to the Witch. Other tactics to kill a Witch in this Mutation include using a Molotov to light her on fire, run away and hopefully let her die from the fire before she reaches the Survivors.

A bile bomb, if used from a long distance, can frighten the Witch into running away, although she may turn up later again on the same level. If incapacitated , Survivors will have access to a Pistol until helped back up on their feet, upon which they will only have access to the Katana.

Smokers are problematic at long range, as unlike the Chainsaw in Chainsaw Massacre , the Katana can only cut the tongue of the Smoker just before it hits the Survivor with extreme timing and aiming, and knowledge of which direction the tongue is coming from.

Stay together and immediately melee shove or attack the Survivor who has been caught to free them. Hunters can be deadstopped melee shove them in mid air as they leap towards you which will stun them momentarily and set them up for a quick kill with a swipe from the Katana. Jockeys are harder to deadstop, so move backwards as you see them leap before shoving them to stun, followed by a swing from the katana to kill them.

The Tank may be the most horrific enemy of all when faced with only a Katana. As Molotovs still spawn, Survivors may wish to ignite him and run for it, as the Tank's speed will be decreased by the flames. This may not work if Survivor Bots are on the team, as they will bravely face up to the challenge and attempt to kill the Tank even if armed with a Katana.

If this happens, and you chose to join in, attack the Tank from his back if possible. Special Infected spawn earlier than normal and at an accelerated rate. This may cause some unusual problems see below.

This means the Survivors are in danger before they even start talking to the original Survivors. If the three see any Special Infected in their range before the Survivors have activated the lift down to where the generator is, all three will immediately draw Pistols out to shoot them. Bill 's body will not have his Assault Rifle next to him. In this Mutation, the normal cap of four Special Infected at any one time has been raised to eight.

In addition, the spawn rate of Special Infected has also been raised greatly. Often when the Director spawns a group of Special Infected, you can expect three to six of them in each group. The possibility of double Special Infected which is an oversight in most Campaigns played normally can occur anytime during the Mutation. It is possible for an entire team to be incapacitated in one go, especially if the Director spawns only pinning Infected in that group.

Be extremely cautious and be prepared to save your allies. Keep moving! Just because you killed the Special Infected doesn't mean that they'll stop spawning.

At the start of each level, you may want to cover as much ground as possible. Often when Special Infected spawn, it will be very hard to push through them, especially on higher difficulties. Common Infected are the same as usual in a normal Campaign. Due to the increased spawn cap and rate of Special Infected, panic and crescendo events should be dealt with extreme caution, as teams can be quickly overwhelmed by sheer numbers.

Tanks should be dealt with carefully in this Mutation. During a Tank fight, as long as players do not try to run past him to progress deeper in the map, no Special Infected will spawn. As such, never outrun a Tank apart from the Bridge finale , as doing so will result in a group of Special Infected appearing and they may delay the team to allow the Tank to catch up.

Be prepared to deal with Special Infected once the Tank dies, as they'll start spawning after his death. This mutation is similar to Hard Eight , except the Common Infected are no longer present to impede the team. This means that the threat of Boomers has been significantly reduced, as their bile is only dangerous against incapacitated Survivors.

However, Special Infected spawn at an increased rate with no cooldown. This means that once a Survivor leaves the safe room, they will immediately start to spawn. Like in Hard Eight, it is mandatory to stick together, and abandon incapacitated Survivors if necessary. Be wary during a Tank fight, as the team will often need to fight Special Infected at the same time.

Players will always start off with a Magnum, though it can be exchanged for regular pistols or melee weapons. Because of the increased presence of Special Infected, the Magnum should never be swapped out for an standard pistol or melee weapon.

The only exception to this is the Chainsaw, as it can save the player from most of the Special Infected. The lack of enemies also means that your Chainsaw should not run out of gas.

Molotovs should take higher priority over bile bombs as they do little to hamper the Special Infected. Tanks and Witches can spawn in a manner similar to those in Versus. All you really need to do are stick together and watch out for Smokers, Hunters, and any other Infected that is able to inflict damage to you and can only be removed by another Survivor.

It is recommended to avoid Witches at all costs except if your team has chainsaws to kill her instantly or shotguns to cr0wn her. Boomers can be very dangerous in finales or Crescendo Events, and Spitters can be very dangerous against stationary and cornered Survivors. Tanks are possibly the epitome of death in this mutation. In this Mutation, you will only have access to the M60 and a Magnum.

While ammo piles exist, they will be useless as the M60 cannot be refilled by ammo piles - not that it makes much of a difference, as in this Mutation, the Survivors' main weapon has infinite ammo. Other guns and melee weapons do not spawn in this Mutation. This will also include places like Whitaker's Gun Shop , which will be devoid of all guns, only having the ammo piles and laser sight.

Taking Incendiary ammo or Explosive ammo will upgrade the next bullets which will be shown by the decreasing amount of bullets left in the M60 every time the gun is fired , after which, the M60 will revert back to unlimited bullets. Notice that if you take another ammunition upgrade before using up the previous ones, you will not get any extra upgraded bullets, but just change the old upgraded bullets.

For example, if you have 50 fire bullets, and you use an Explosive ammunition upgrade, you will only lose all fire bullets and get 50 frag bullets. It is advised to use or waste the remaining upgraded bullets before using new ammunition upgrades.

Remember that using Explosive ammunition up close can cause friendly fire damage to yourself and your teammates if they are too close to where the bullets impact. Survivor Bots, as usual, cannot cause friendly fire damage unless they accidentally shoot something like a propane tank.

It is still advised to use it just like using normal automatic weapons in normal campaigns. Aim quickly but carefully, fire in single shots or bursts. This helps you avoid friendly fire and increases accuracy at long range. Only use full automatic when fighting hordes, Tanks , Witches , and Chargers. Remember to shove if Common Infected get too close, and move your position so that other Survivors are not behind your target as you open fire, unless you are able to consistently fire off single shots from the M If boxed in by the Common Infected, whoever is at the front should crouch so that Survivors from behind can fire over their heads.

With four unlimited M60s, taking down Tanks will be easier than normal, especially as the M60 with unlimited ammunition is the fastest gun at taking down the Tank on all difficulties. Survivors may have to watch out for friendly fire if there is not enough room to maneuver. Witches may prove a little bothersome as nobody will be able to cr0wn the Witch.

In this case, Survivors may have to all shoot at her from a distance at the same time and take her down before she reaches the Survivors. Using a Molotov will help in reducing her running speed slightly, as well as giving the Survivors a fiery target to shoot at. For other tactics involving taking down the Witch without using a shotgun, see the section on killing the Witch on her article. Alternatively, if possible, just run past the Witch at the same time or in pairs with flashlights off to avoid fighting her, especially on Expert difficulty.

If a Hunter or Jockey gets too close, it may be preferable to shove it to death due to the M60's damage, especially at higher difficulties. If any Survivor Bots are on the team, they can shoot the Special Infected to death without fear of friendly fire. Remember to shove it to expose the back or move your positioning. Laser sights will increase the accuracy of the M60, especially when shooting on the run.

Be sure to look out for places where they usually spawn at, and get the entire team to upgrade their M60s. If Survivors are incapacitated , they will have access to a Magnum, which works better than the usual Pistol s at taking down Common Infected attacking while Survivors are downed. While the Magnum could be used for doing long distance shots, the M60 can also do long distance shooting by crouching.

This makes the Magnum basically only useful when Survivors are incapacitated, or when attempting to do single shots at long range if the user is unable to gently squeeze off single shots from the M Throwable weapons such as the Molotov , bile bomb and pipe bomb still spawn. For all intents and purposes, the Mutation plays exactly like the default Campaign with no changes to the Infected. In this Mutation, it will play almost the same as Realism and as such, many of the tips for playing Realism will apply to this Mutation.

With the lack of ammo piles, however, this will mean conservation of your existing ammo. Use your secondary weapon, be it a Pistol or melee weapon often.

Don't get too attached to your gun, especially if it has a laser sight on it. Be prepared to swap it as soon as you come across new guns. The Magnum works well against the Common Infected due to its one-hit-kill properties carrying over to Realism.

The need to stick together and survive is even greater in this Mutation due to the Realism rules and the main rule of Iron Man Mutation, which is if the whole team is incapacitated or all the human players die, the team will be booted to the lobby.

In this Mutation, Infected players will spawn as Tanks only. There are no other Special Infected to worry about. However, having to deal with four Tanks is extremely troublesome. Common and Uncommon Infected still exist. They can and often will slow you down, so try to eliminate them before they swarm you.

For these purposes, players should be equipped with shotguns and melee weapons. First aid kits have been removed, with all spawn points for them being replaced by pain pills. Simply put, due to the nature of one Tank being bad enough, let alone four, a solid tactic is to group together and keep running. Keep moving towards the safe room.

DO NOT deviate from the main path under any circumstance, as it will allow the Tanks to catch up to you. If a teammate is incapacitated, in most circumstances during this Mutation, they will have to be abandoned, as the time reviving them can be more than enough for a Tank to catch up to you. If all the Tanks are dead or very far behind, it is possible to revive and incapacitated player. Make sure you use an Adrenaline Shot if you have one to shorten the time needed.

During Crescendo events and finales , keep moving, and never stay in one spot. Keep moving so the Tanks cannot gain the advantage. Tanks during this Mutation have health, compared to their normal Versus health of If forced to take on a Tank, concentrate fire on one to bring it down faster.

A Molotov will be extremely useful to panic the Tank players if it can be used at blockage points to either prevent the Tanks from running through, or forcing them to run through so they catch on fire.

Gas cans serve a similar function with a longer lasting fire, except they need to be shot first. Bile bombs may also be handy if found to slow down the Tanks with Common Infected, as well as blurring their sight for a limited time. In The Bridge , Tanks will spawn in the safe room before the bridge has fully lowered, leaving all Survivors open to attack with nowhere to run. Setting the safe room floor on fire with a Molotov will at least help slow them down if the Survivors can survive the initial onslaught, as they will all eventually die from the flame and wait for respawning.

The Passing and Dead Center finales are the hardest to complete, as the Tanks will be waiting for the team when they disembark, often resulting in human team getting incapacitated before they can complete their objective.

Should the human players manage to escape, they will also have to grab gas cans to complete the objective, leaving them defenseless against the horde and Tanks. In this mutation, the main attacking Special Infected are Hunters.

Being able to deadstop or kill them from afar will be key to survival. You will still have Tanks, Witches and Common Infected in this mutation. There is a short delay after leaving the safe room before the Hunters start spawning much like the Tanks in the Tank!!!!!

Hunters tend to spawn together in groups of four. As they are all pinning infected, it may be possible for the entire team to be overwhelmed by sheer numbers. Stay close to each other and immediately rescue each other if someone is pinned. Be alert! Hunters begin crouching the moment they come into close proximity with Survivors, causing them to growl as a warning.

In addition, keep an eye and ear out for Hunters during horde attacks. Up to 6 Hunters can be present in this mode. In this Mutation, the player is only armed with a Magnum , which can take down Common Infected and Boomers in one shot. However, attacks of the Common Infected have a 15x multiplier. On Easy, it takes 7 hits from the front 14 from the back to incapacitate the player. On Normal, it takes 4 hits from the front 7 from the back to incapacitate the player.

On Advanced, it takes 2 hits from the front 3 from the back to incapacitate the player. On Expert, a single hit to the front or back instantly incapacitates the player. Move fast, and try not to use the flashlight if possible, as it will alert Common Infected faster within their proximity.

Try to avoid killing as much Common Infected as possible, as it will prevent as much Common Infected from appearing in front of you. In some cases, it will be better to run and gun, and others just sit in a corner and shoot.

Do the former if there are not many Infected in the area, but be careful, but do the latter if vomited on or in a Crescendo Event without environmental advantages such as the fire in The Hotel or throwable items. Try to also make as much use as possible of throwable grenades preferably in Crescendo Events. Classic Campaign Co-op. The infected carry disease, filled with a variety of symptoms.
