About this game
I'm sorry! We have limited resources and can only develop 2D to transition, but our game will still include DMZ gameplay and more! We first introduced the single player mode of RougeLike+survival. We will launch more fun game modes in the future!
The mode that can be played now: single player RougeLike survival, the infinite world is filled with infinite possibilities!
Currently, both the main program and art resources are handled by Fltoto alone, so the resources are limited... However, the original intention will not change! Our goal is to create a good player community where players can actively express their opinions!
Secret code: 929194147
As a survivor of a lost world, you need to do your best to survive in this infinite world! Surrounded by unknown infected individuals, there are also cute little rabbits. Due to the failure of a certain military weapon experiment, this super large experimental base was destroyed. As a member of this experimental base, you successfully survived, but you lost your memory! The instinct to survive drives you to persevere.
