Ambrosia has announced a Mac OS X version of its space-age arcade shoot-'em-up classic, Maelstrom.

The port is available as a free download

The game was originally developed by Andrew Welch for Ambrosia. It ran on older Macs, supported 256-colours and involved flying a spaceship through asteroid fields. Programmer Sam Lantinga then ported the title to Linux, introducing network play.

Lantinga has ported the Linux version to OS X, taking advantage of both operating systems' Unix core.

Ambrosia isn't supporting the Mac OS X version of Maelstrom, but the title is available for download.
