This is something I found on youtube and I don't know what game it is, or even if it's a game at all. Does anyone know what this is?

As the video description says, it's a fan-made mod for Unreal Tournament to make a 3D Sonic fan-game. You wouldn't think that you could make a Sonic game out of a shooter game, but the Unreal engine actually is quite versatile. No, that isn't official in any way other than that someone probobly hacked the three dimensional Sonic models from one of the Sonic Adventure games, and put it into this mod.

ok. Thanks, DP. I wasn't sure about it because it didn't lokk like anything I've ever seen. But Super Sonic looked cool...

Personally, though I can't say much for the taste of music used for that video, that does seem like a pretty cool mod. I just hope the music in this preview video doesn't reflect the kind of music one might expect to hear in the mod.

Man, anybody else remember those really old Doom and Wolfenstein 3-D mods? XD It seems like mods nowadays are considerably more sophisticated.
