Author's Description: 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.

The latest release is 0.1.4 (September 19th, 2010). Main features:

* It's portable! No installation is required!
* Sonic-style physics (360° movement engine)
* Available in 9 languages: English, Portuguese, French, Polish, German, Czech, Dutch, Indonesian, Italian
* 2 levels + innovative items + extras
* You can create your own levels using the built-in level editor
* You can make your own custom items, enemies and bosses using our object scripting system
* MODdable capabilities
* Good performance even on old computers

It's been some time since we're replacing all the "ripped" content by original user-made resources. Things are moving forward, but there is still some work to do. We need more contributors.

0.1.4 is the last release of Open Sonic. The next version will be Open Surge 0.2.0, a free game inspired in the classic Sonic gameplay featuring nothing but original user-made free (as in freedom) resources: graphics, characters, sound effects, musics, plot, etc. A new physics system is planned for the next version as well.

Public Opinion
Overall Rating: 10.0
  • 10I was surprised by just how great this game is. I'd wager to say the quality is on par with that of the original Sonic games. The controls are near identical to the originals (the only major difference I noticed was that Knuckles takes a while to stand up after flying then landing).
