The 3D catalog: game boxes on wooden shelves, with the cat sitting at the counter next to its greeting.

The catalog in 3D

The same catalog has a room you can walk around in. The cat behind the counter is the AI Catbot, and they pick real games from it when you tell them what you feel like playing. Nothing is for sale, here or in there. Go in from here and this game is already out on the counter, with more like it waiting on the shelf next to it.

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.
