Maelstrom was originally a classic Mac OS game, first released as shareware in 1992 by Andrew Welch of Ambrosia Software. Ambrosia gave the source to Sam Lantinga, who released Maelstrom 3.0, a SDL port under the GPL, in 1995. The game assets were released under the CC Attribution license in 2010. The latest version of the unmodified SDL port is available at http://www.libsdl.org/projects/Maelstrom/. This repo is a fork off of the SDL port. There are two primary changes: 1. The code has been updated to compile on modern machines. 2. The retro-thrusters powerup has been modified. Instead of being constantly active, and thus constantly slowing your ship, they are bound to a key, and only activate when that key is pressed. Original Maelstrom 3.0 README Maelstrom 3.0 Maelstrom 3.0 is a GPL'd port of the original shareware game for the Macintosh. It is a fast-action, high resolution (640x480) asteroids-like game, with detailed graphics and original sounds. The GPL version of Maelstrom is not supported by Ambrosia Software, but is recommended highly! :) The latest GPL'd version of Maelstrom is available at: http://www.devolution.com/~slouken/Maelstrom/ The original Macintosh version of this game is available at: http://www.ambrosiasw.com/ Check out the file "INSTALL" in the source distribution for instructions on building and installing Maelstrom from source code. Check out the file "README.network" for information on how to play networked Maelstrom. See the file "README.options" for more information on the command line options and compile-time features. The Docs directory contains FAQs, press-releases, and technical notes about the Maelstrom porting process. Enjoy! -Sam Lantinga (slouken@devolution.com)
