DEADGRID is a minimalist zombie arena shooter — pure, intense arcade action with real multiplayer. THE CLIMB A campaign ladder thousands of levels deep, and no two rungs are alike. Every level rolls its own horde, its own weather, its own rule and its own goal: one-hit-point runs, total blackouts, meteor storms, assassination contracts. Two modes break the pattern — INFECT, where you ARE the outbreak and hunt the survivors down, and FREE FOR ALL, where everyone carries the same gun and only one walks out. 1,080 WEAPON FINISHES Thirty collectable liveries — GOLD, ONYX, SYNTHWAVE, NOSFERATU, VOIDLINE, RAINBOW and more — across all 36 weapons. Every third rung of the Climb pays one out. Locked finishes stay secret until you earn them. TWELVE HANDCRAFTED ARENAS Fight through Times Square, Shibuya Crossing, the Champs-Élysées, Copacabana, Stonehenge, the Taj Mahal, Chichén Itzá and Terreiro do Paço — plus four arenas of our own: The Garden, Sporewood, Rustyard and Cindermaw. Lava rivers, container mazes, neon crossings. Every layout is placed by hand, never generated. SURVIVE THE APOCALYPSE Endless waves of the undead. Every run is permadeath — beat your best in kills, waves and time survived. RANKED 1v1 — THE ARENA Duel real opponents in last-one-standing combat. Buy rage zombies and send them hunting your rival, earn a random upgrade every round, and climb 8 divisions to the top of the global ladder. DUO CO-OP Team up with a friend or matchmake with a stranger. Shared horde, shared glory — revive each other and see how deep two survivors can go. ARSENAL OF 36 WEAPONS Pistols, SMGs, shotguns, rifles, snipers, launchers, energy weapons, flamethrowers and wilder things — each with its own 3D model. Loot weapon crates mid-run and build your loadout on the fly. NINE ZOMBIE TYPES Walkers, runners, tanks, boomers, jumpers that vault your walls, fire-spitters, bladesmen who cut bullets from the air, gaolers with hooked chains and summoners who raise the dead. Smart pathfinding routes them around cover — they hunt, they don't just shamble. TURRETS & DEPLOYABLES Three turret types, barriers, claymores, explosive barrels and the legendary clapping monkey. Build choke points, then watch the horde walk into them. PROGRESS THAT LASTS • GAME PASS: a 101-tier season track with exclusive skins, chests and emotes • MISSIONS: endless ladders that pay pass XP with bonus chests on every claim • SPECS: permanent lifetime upgrades that make every future run stronger • 42 SKINS to unlock — from the humble Rookie to floating war gods • 32 EMOTES to talk trash in style COMPETE WITH THE WORLD Global leaderboards, a top-1000 board, friends list with live presence, duo invites and player profiles. Daily streaks keep your fire burning. PURE PERFORMANCE Optimized for smooth 60fps. All game audio is synthesized in real time — zero audio files, tiny download. No ads. No pay-to-win. No timers. Just pure arcade zombie survival. Download DEADGRID and see how long you survive.
