Repulse is a fixed shooter arcade video game developed by Crux and published by Sega on June 1985. In the game, players battle against the invading Aquila nation to defend Earth from world domination. The title is notable for being created by most of the same team that previously worked on several projects at Orca and Crux before both companies declared bankruptcy, after which a group of employees from the two gaming divisions would go on to form Toaplan.
