OpenSonic: The Free Version Of The Famous Sonic Game

OpenSonic is an open source and cross platform (works on Windows, Linux, Mac OS X (experimental) and Dreamcast) game based on the famous character "Sonic the Hedgehog". It introduces a different style of gameplay called cooperative play, in which it's possible to control 3 characters simultaneously. Unlike most similar games, Open Sonic provides a greater level of interaction between the player and the levels. It's more than just a jump'n'run; the user must come up with some strategy in order to get through the levels.
