I don't care how nostalgic it makes people feel -- Altered Beast is bloody terrible. It's possibly one of the worst beat 'em ups ever conceived, and as if to rub that in the faces of those who don't know any better, Sega expects you to unlock it in Sonic's Ultimate Genesis Collection. That's just cruel.

There are a number of unlockable games in Sega's latest Genesis compilation, none of which are actually Genesis titles. Instead, the unlockables are from the Master System or Arcade. Since I know you're all eager as blimmin' heck to know what they are, here's a list of achievable games:

Golden Axe Warrior (SEGA Master System)
Phantasy Star (SEGA Master System)
Alien Syndrome (Arcade)
Altered Beast (Arcade)
Congo Bongo (Arcade)
Fantasy Zone (Arcade)
Shinobi (Arcade)
Space Harrier (Arcade)
Zaxxon (Arcade)

While you're here, we have some screenshots of videogames, just in case you've forgotten what stuff you've played a million times before actually looks like. We have six images of Shinobi III, while the rest of them come from these unlockable arcade games. None of them were Altered Beast though, so now I have to raid Google for a relevant picture.

THANKS SEGA FOR THAT ACTUALLY THANKS!
