Gravstorm is a Windows/Raspberry Pi/Android version of the Commodore Amiga indie game "Turbo Raketti" (by Heikki Kosola). The game is best described as a multiplayer variant of "Thrust". The players steer spaceships in a cave, flying around trying to shoot each other down.
Gravstorm supports up to 4 players splitscreen (on Windows/RPi only) and network multiplayer (all versions).
The game is not an emulation, but reprogrammed from scratch and released for free.
