The world is in ruins! The zombies is approaching! Don't panic! Join the Doom Sweepers! Become a secondary arms dealer and make a living by clearing zombies!
In this world devoid of sexual activity, filled with hunger, chaos, and insect food, but as long as you immediately join an A-grade arms company and become a sweeper, you will get everything!

Yamato, a girl who has lost her family, and Roche, the top service boy of SOPRT BOY, have purchased a second-hand military vehicle from an A-grade arms company and embarked on the journey of the Sweepers.

In these 20 minutes, all you can do is survive, clean zombies, collect samples, and exchange them for cash.

As the cleaning progresses, you can unlock a variety of airdrop military support! You can even "watch a show" to upgrade your weapons.
