Doom Sweeper

In a ruined world overrun by zombies, Yamato and Roche set out as sweepers in a second-hand military vehicle. Players take on zombie waves while trying to keep their stronghold standing.

Each run lasts about 20 minutes. Players collect samples to exchange for cash, choose and upgrade weapons and defenses, and combine equipment to increase their firepower. Airdrop support can add further military gear.

Between runs, cash and achievements contribute to unlocking shop items and other rewards. Different characters have distinct abilities, and the game also includes lasting upgrades and a gallery of CG images.

Players who enjoy the game often point to its weapon combinations and the satisfying power spike when a build comes together. Some also like its mix of survivor-style action and tower defense, along with the pixel art and dark humor. Other reviewers find the difficulty, upgrade choices, and drawn-out runs frustrating, so these positive reactions are not universal.
