Don't buy it man! I'm being fucking serious here, I want my fucking money back, what a fucking rip-off! Holy shit this is fucking unbelievable, it's just a long ass boss fight, they made it hard as hell so people wouldn't blast through it in 15 minutes. Holy hell, you do some platforming in a boring cave, fight the same boss twice and that's it, I can't fucking believe this shit.
Oh, and the ending fucking sucks, it doesn't add anything to the main game's ending, hell, it doesn't add anything period. I really wish I hadn't bough it, I was so confident that this would be good, never again.
