SteamAbout Deadship Protocol
Deadship Protocol is a bullet heaven for 1–4 players. Play online or on the same couch, or take on the ship alone. Fight hordes of energy-feeding aliens, recover eight Protocol Cores, and choose powerful upgrades before the reactor runs out of power.
1–4 PLAYER CO-OP
Play online or on the same couch with up to three friends, or face the run alone. Split up to search the ship, hold the reactor, and revive downed crewmates. Someone must stay near the reactor.

LEAVE THE REACTOR TO SAVE IT
The Purge needs eight Protocol Cores, and every one lies beyond the reactor room. Leave the ship's last power source undefended, push through the swarm, and carry each core home before the aliens drain it dry.

BUILD A SCREEN-CLEARING ARSENAL
Weapons fire automatically, so focus on moving, dashing, and aiming your Operator's emergency special. Choose from four Operators and combine more than 20 upgrades into coil fire, caustic payloads, drones, and critical hits.

ARM THE PURGE
Each recovered core makes you stronger and brings the Purge closer. Bring back all eight, survive the Devourer, and finish the run in about 12–18 minutes. Generated ship layouts and changing upgrade choices make every attempt play differently.
