Leveling is the process by which a player gains levels and unlocks new items and promotions. By participating in a mission, a player is rewarded with experience points, and when a certain amount of points is reached, the player gains a level. Reaching a new level always unlocks a new piece of equipment or a weapon. Every player begins the game at level 1 and can attain level 27 (in Alien Swarm) or level 34 (in Alien Swarm: Reactive Drop), which is the maximum level. A player can reset their level back to 1 after reaching max level by electing to receive a promotion.

Individual characters do not level; rather, a player's level is global, and any items unlocked are accessible to all characters who can use them.

Notes[]

  • An equipment item is unlocked upon reaching each even-numbered level, and a weapon is unlocked upon reaching each odd-numbered level, up to level 27. Levels 28 through 34 (Alien Swarm: Reactive Drop only) do not follow this pattern anymore.
  • The amount of Experience Points required per level is multiplied by two after the fourth promotion, by four after the fifth promotion, and by six after the sixth promotion - see the table below.
  • It is possible to gain two levels at once after completing a mission.
  • The achievement Armory Access is earned by reaching max level for the first time.
