The most annoying level

[Baegal]

Sonic's last stage in Sonic Adventure 2

Crazy Gadget ? Cause that bitch is infinite.

On that subject: Mad Space.

FUCK. ALL. THAT. SHIT.

Or Security Hall with it's five minute time limit, especially back when my game was glitched or some shit and the camera would break even more than normal and would get stuck behinds walls so I couldn't see where I was going for minutes at a time.

I know I'm a little late to say this, but I actually LOVED Security hall. That (along with cannon's core) was probably my favorite level in that game.
