Co-op Survival for up to four players: host a public game, join one from the list, or join a friend through Steam.

The team shares XP Molecules and levels up together, and everyone picks their own loot.

Downed players come back at half health when the next wave starts; the run ends when everyone is down.

Every pickup shows a short notice in the lower left.

A 10 second intermission after each Campaign round; press F to move on early.
