RescueNauts is a game for one or two payers. Why one or two players? Well, there are two characters and roles to play in the game. Fast paced, arcade action that comes from the old school of 'sitting next to your buddy, playing a game, and punching them in the arm when they let you down'.
This is RescueNauts V1.1 for Linux. Includes tweaks and updates to gameplay, as well as a new tutorial for new players.
