In 199X the world was at peace... until it all hit the fan!
When It Hits the Fan is an action arcade twin-stick shooter for PC and arcade that you can play with a friend that was inspired by many classic arcade and SNES/Sega Genesis era games.
It features four apocalypse scenarios happening all at once:
Zombies spilled out into the city streets...
AI in military grade robots went haywire...
Demons started pouring out of hell...
And finally, aliens started invading the planet!
