About the game
Red Planet Rampage is a dieselpunk western-themed arena shooter where robots face off on Mars with wacky modular guns. Win gun parts in auctions and assemble a unique combination among hundreds of possible weapons!
The game is developed by volunteers at Hackerspace NTNU and is free and open source!
The robots responsible for terraforming Mars have donned cowboy hats and started wreaking havoc with staged shootouts and competitions where they auction off rudimentary weapon parts assembled from scrap. Terraforming Inc. is still investigating the cause of this disturbance, but rumors point to a fateful upload of a western film.
