The instructions are in-game. This game is quite dark so I apologise, if it's too dark please notify me in the comments so I can change it. It is also quite buggy and hard but Please enjoy! There are only 4 levels but they are MEGA HARD.
Thank you my brother for asking for a zombie apocalypse game and to the creator of Zombie runner who I borrowed some script ideas. Please check out that game it's hard but good!
