Zombie Crawlerz

Inch down a grid corridor lit by lamps that flicker for reasons no one will explain, kick open colour-coded doors with keys you'll inevitably find in the wrong order, and survive the rooms beyond by playing cards that cost ammo you never quite have enough of. The zombies shamble across a turn-based grid the AI is fairly confident is 'tactical.' Find the master key, reach the exit, and try not to wonder why a condemned building has fresh wallpaper banners running down every hallway.
