Sonic Unleashed (released as Sonic World Adventure in Japan), is a video game in the Sonic the Hedgehog series developed by Sonic Team and published by Sega for multiple platforms in 2008. The game follows Sonic the Hedgehog as he attempts to restore the world to normal after his nemesis, Doctor Eggman, splits the world into pieces, as well as his struggles with his new beast form, Sonic the Werehog. Gameplay features two distinct styles, with each being played either during daytime or night-time. Daytime stages incorporate Sonic's traditional platforming and trademark speed, with a combination of behind-the-back third-person viewpoints and 2D side-scroller platforming; gameplay seamlessly transitions between these two views. Night-time levels see Sonic transform into the Werehog; gameplay slows down to accommodate greater platform play, and involves combat against waves of enemies using the Werehog's brute strength.

Problems

No Video

Sonic Unleashed has very unusual depth clipping issues. For years, these problems were fixed by the "Sonic Unleashed hack", a very messy and annoying projection hack. In 4.0-564, this hack was removed so a proper fix could be found. This broke OpenGL compatibility, but D3D continued to render since depth clipping was broken in that backend. However, this clipping bug was fixed in 4.0-3748, leaving this game broken in both backends. It was believed that it would be ok since the projection epsilon fix in 4.0-4451 fixed all of the other sonic games that relied on the Sonic Unleashed hack, but Sonic Unleashed itself is presently unaffected. There is no solution at this time.

3.0-415	Mac OS X 10.6.8	Intel Core 2 Duo @ 2.13GHz	nVidia GeForce 9400M	Playable, but in day stages, sound stutters. Avg. emulation speed is about 60%. When using a real Wiimote, boosting is difficult on the ground; it has to be shaken at just the right speed or it won't happen. It's easier to just use a Classic Controller instead.	Ac
3.0-458	Mac OS X 10.7.4	Intel Core i7 @ 2.6GHz	nVidia GeForce GT 650M	Nearly perfect with default settings! There are bits of stutter here and there, but speed has never dropped below 80% as of now. Much better than my previous attempt above, though sound still stutters at random intervals (accompanied by slowdown).	Ac
3.0-594	Windows 7 x64	Intel Core i7-2630 @ 2GHz	nVidia GeForce GTX 460M	Playable speed, usually around 60-80%, daytime stages result in noticeable sound errors.	DiscoBiscuit
