I don't think it should be combatless, but guns just don't feel like a natural fit to me. You're slow and anchored to the ground while using them, which is fine for balance reasons but doesn't really make for anything entertaining. I'd much prefer they just deepened the hand-to-hand stuff and generally kept the whole thing free-flowing.
Same.
The hand to hand combat was pretty basic in the first and that does seem like an angle they could play up for more mass appeal.
I didn't really have a problem with enemies having guns, you could just speed by them 98% of the time, so they mostly just worked as a timer.
