About

Classic Maelstrom

Features
Read full description

Maelstrom is a licensed open source port of the original shareware game for the Macintosh by Ambrosia Software, Inc. It is a fast-action, asteroids-like game, with classic pixel graphics and original sounds. In addition to being a faithful reproduction of the original game, this version adds game controller support, mobile touch controls, and both cooperative and competitive multiplayer action. Features: Kid Mode Clicking the "kid mode" icon next to the play button will enable an easier play mode which will add the retro-thruster prize and automatically shield you as long as shields are available - but beware the Shenobi ships! Their shots will not trigger the automatic defensive systems. Achievements and high scores are not available while in this mode. Multiplayer You can host or join a multiplayer game from the main menu. Up to three players can play at once, and they can be any combination of other players on the local network, and connected controllers. Easter Eggs The classic easter eggs from the original game are all there, and it's up to you to find them...
