You are the virus. Turn a fragile malware process into a screen-clearing outbreak—solo or in online co-op.

Packet Plague is a neon bullet-heaven roguelite inside a hostile computer network.

Move, dodge, and collect XP while your payloads attack automatically. Draft

upgrades, combine weapons, and evolve your build as the security response escalates.

Build your outbreak

Experiment with 22 payload weapons: beams, orbitals, missiles, mines, summons, and

more. Pair weapons with passive upgrades to unlock evolutions and discover the

combinations that fit the way you move.

Survive the security response

Fight across six network sectors with different layouts and hazards. Face phased

bosses while keeping an escape route through the swarm. Fifteen minutes is a

milestone, not a finish line. Keep the run alive for as long as you can.

Breach together

Play solo or team up through Steam online co-op. Share XP and the run, but choose

your own upgrades and build your own arsenal. Coordinate before the breach;

players join in the lobby, not halfway through a run.

Come back stronger

Turn completed runs into permanent progression. Unlock eight malware characters,

invest in the Evolution Grid, and take on new loadouts and challenge protocols.
