Survival Tactics These are methods for survival during specific conditions, such as fighting certain bosses, and surviving in events. First off, I would just like to say that this is opinionated, but are strategies that many players use. All player input is appreciated.
Apocalypse[]
This is a game mode based entirely on survival, there are several tactics for surviving a very long time to gain maximum points.
Team work
Team work is essential to victory, covering weaker allies while they regain health, and take on bosses in groups to minimizes casualties. Any medics should be protected while they heal weaker allies for combat. Always remain in groups, never stay alone, it is easy to be swarmed while alone and unable to kill zombies
Turrets
Do not be sparing with turrets, set them up in strategic choke points to kill more zombies, with minimum ammo consumption. Turrets will help wear down bosses and kill off hordes, making it easier to focus on the boss. Crowd control is vital to victory, high pierce turrets are the best for this, and make sure that they are by a choke point, this will maximize killing power, and also help with masteries.
