About DEADBLOCK: Outbreak
DEADBLOCK: Outbreak is a tactical zombie shooter with a six-sector campaign. Survive ten waves to secure each sector and unlock the next. Explore fields, enter buildings, climb raised terrain, and scavenge supply caches. Earn upgrade points at checkpoints and choose between three pairs of competing paths: weapon power or explosives, armor or mobility, recovery or supplies. An icon-based tree shows installed ranks and excluded branches. Completing a sector saves earned gear and your build in the current browser; a failed attempt returns you to your last secured loadout.
Five weapon families share one scrollable loadout with barrels, grenades, walls, claymores, and remote charges. Walls and claymores are available from the start. Snap barricades together, rotate them, and reclaim a segment to reopen your escape route. Friendly shots pass over low barricades; enemies can damage and destroy them. Only the pistol has infinite ammunition, and no weapon needs reloading. Chain kills faster as the multiplier rises to unlock more equipment. Runners, ranged devils, armored enemies, volatile zombies, and bosses escalate the threat.
Move with WASD or arrows, aim with the mouse, click to fire or deploy, and use the wheel to select any equipment. Space dashes; Q rotates walls, F reclaims them, E opens caches, and Tab shows your build. Touch controls support movement, auto-aim firing, and equipment selection. Completed sectors and failed runs submit scores to the public leaderboard.
