Maybe I'm missing something but man I'm having a tough time with this game. Even taking into account my generally crappy skill level the games seems way hard! Can't seem to get past the weird boy at the end of the second level.

Anyone else having the same experience?

What Space Marine are you using? The levels seem to be a bit suited towards either ranged or melee, depending on the enemies, though all can be done with either on your own.

What exactly are you having trouble with? The game does have a couple of difficulty spikes, though it does help to manage your power ups.

I made it through most of the game with the Vangaurd Marine pretty easily. There were a few spots that I had trouble with though. Any spot in particular you're having trouble with?
