Undead co-op reboot
Hold the yard. Drop the horde.
Zombie Siege is now a room-based co-op survival game with shared waves, mission stages, uplink objectives, plague nests, extraction holds, a much larger yard with layered rooftops, mouse-driven hitscan gunplay, frag grenades, and heavier visual and audio feedback.
Host, join, or practice solo
Rooms generate invites instantly, and solo uses the same core rules as live rooms.
Aim and survive
Turn with Q/E or Left/Right, aim with the mouse, throw a frag with Shift, and use the rooftops, decks, and stairs to cut down each mission phase before the yard collapses.
Invite link
Host once and send this link or room code to your squad.
Arcade Lounge
Open the lounge in a new tab or drop this zombie room there instantly.
Advanced connection settings
Host a room to generate an invite, join by code, or start a solo siege instantly.
Why it feels better
Rebuilt gunplay
The rifle, SMG, and shotgun now hit instantly along the shot line, with bigger muzzle flashes and stronger tracers that read much better in motion.
The run now escalates through relay captures, plague nest sweeps, and an extraction hold instead of feeling like an endless empty loop.
Crawlers, spitters, brutes, and bosses now mix with the base horde so the fight forces real movement and target priority.
