Another Unity Prototype: MazeWar
So this is a remake of an old Atari game: http://joshv.itburns.net/MazeWar.html
The basic ruleset is you can have only shot out at a time, hitting a wall causes it to explode shortly thereafter, sending shrapnel in the cardinal directions it wasn't shot from. If a projectile hits a projectile, it causes a backsplash.
Still has a few things to do, player/player collision is borked, for example. I should add difficulty, number of zombies, scoring and if I really want to go nuts, I'd add multiplayer of some sort. I should probably try adding mouse controls, and maybe do some actual AI, the current zombie is really simple (doesn't even really do pathfinding, though I don't believe the original game had all that much either, it mostly speed up their move speed.
The original game, by Mark Price is here:
