Blackgate was a huge disappointment for me. I mean, it's a sidescrolling metroidvania style game. Gotta be great, right?
Meh. It's not terrible, but after loving Arkham Asylum and being a huge fan of metroidvanias, it's just mediocre. It's a sidescrolling game, but you move around in a 3d space. It effectively makes the map worthless (or least, hard to understand). I could forgive it if the gameplay was actually interesting, but it's not. You're basically on autopilot as you just press a button to get to a ledge with your hook... over and over again.
I dunno, I expected it to be too much like metroid, I guess.
