Imagine Conway's Game of Life, but replace the evolution with fire, zombies and UFOs. Congratulations, you've got Conway's Inferno - a puzzling take on the old zero-player game created at GAMBIT-MIT for the Global Game Jam.

On each level, there are people represented by yellow faces. You need to kill every single one using only a limited number of fires, zombies and UFOs - the fires will spread through people and trees, zombies will spread through the rivers and infect anyone nearby, and UFOs will drag people up the screen.

It's pretty clever stuff and a nice take on the Game of Life. Give it a play at Newgrounds.
