The final boss battle from Sonic Colors, now installed into Team Fortress 2 with this mod.

pretty sure i S-Ranked it guys. okay, now it's REALLY done like i mean seriously finally really done i might release a few patches and updates and stuff, but as for right now you can fight him with almost no flaws (there's a few but they don't get in the way) credit to SEGA for the beautiful cutscene at the end, the models in the video ('cept the scout), and the sounds in the video.
