You just kill a buncha red dudes.

Sometimes you can't see where the red dudes are coming from though which sucks when you die in one hit.

The longer it goes the more the story takes over and the focus becomes less about killing red dudes which isn't as fun since you aren't killing red dudes as much.

I was kinda hoping to be able to type what I wanted at some point.

But hey, you get to kill a buncha red dudes. It's really cool.
