but oddly no boss fight yet and I know it's Metal Sonic which should be fun.
One you "complete" the three stages (both acts) you have to go to the "upper" areas and play through dopey challenges. I can't get through them and really dislike them. Once you clear these challenges you get a key, get three keys from the challenges and you'll unlock the boss.
Every time you "complete" three stages (both acts) you'll have to repeat the process with challenges on those stages.
I swear Sega would be better off just letting gamers play Sonic and not throwing this crap / junk into it.
Yes I got it on the 66% off sale as well.
