Leveling

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.
