Not too easy of a game, but not too hard. It is kinda like a zombie survival, except that you do missions, not just hold off. currently I only have the first chapter. Press "i" on the title screen to view story, controls, etc. If you find something you don't like, or a bug, please report it. It is still WIP.
It is recommended that you read the description.
