So I've started this game, and like every other FPS ever, I auto jumped to the hardest difficulty--Trauma--for the challenge. At the first boss now, and while he's hard, not impossible. But after doing some digging I am seeing that there are some levels not available on Trauma and some are, and I'm pretty damn confused.
I want to play the whole game, really, with as much challenge as I can get (realistically). So which difficulty should I play on? I'm assuming Trauma isn't it, so that does that mean a restart for me?
Thanks a lot for the help. This is an FPS about killing everything, I didn't expect it to become so convoluted!
