Open Surge
Open Sonic has been discontinued. We're working on a new project, Open Surge, a free and open-source game & engine with a trademark / IP of our own.

Welcome!

Open Sonic is an open-source game based on the "Sonic the Hedgehog" universe. 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.

Open Sonic is available for Windows and Linux. The latest release is 0.1.4 (September 19th, 2010). Main features:
