66 Catacombs discovered beneath a city (in America?).
Firstly: Hello, first post 'n whatnot.
About the game: Basically, I plan to have it where, although a normal run 'n gun platformer, I plan it to be possibly a infinite, somewhat procedurally generated, and hopefully creepy game. As for enemies, There would be two ways for them to enter, falling from the shelves, either to crush you, which they would they stand up, or ones that would rise out of the ground. The rest is simple, ones that run or walk, and the way they look, like skeletons, or normal looking zombies. The world would probably be a large hallway like place with uneven ground, possibly lakes (oh boy, swimming zombies), and tunnels going up and down that fall through to get to the next level.
