Nextbot is what will haunt you.
This game has 2 modes "Survival" and "Search for sheets".
In survival mode, you can create up to 50 bots at the same time and adjust their speed and size. You can also play with friends online and communicate via voice chat.
In "Search for sheets" mode you enter a randomly generated level where you have to find 5 sheets.
After that, find a door with a combination lock and enter the code.
You will be chased by bots, be careful, because at every step there could be someone waiting for you:
Obunga
Selene Delgado
Munchi
Ahenobarbus
Yoshie
Chomp man
Quandie
and many others
You can also create your own bot!
Good luck!
