How it feels

It feels like a fast-paced, squad-focused bug hunt where coordinated teamwork and tactical loadouts are key to surviving waves of aliens.

What players say

Players call Alien Swarm a fun but abandoned co-op shooter from Valve. Many say Reactive Drop is the better-supported version to play now. The game is simple and free, and some came only for the TF2 hat.
