Fair enough. With the chainsaw guy I guess my RE4 training kicked in and I just picked away at his health while keeping my distance until he keeled over. Also lured him into the spike trap in one of the houses nearby.
With mobs I found they couldn't catch me as long as I kept moving without letting my stamina run out, while using grenades and explosive crossbow bolts to clear out several at a time.
Again though I played on easy so maybe it's just better balanced there?
Or maybe its balanced in your favor ... because its on easy.
This is sitting on my to get list I'm hoping they port it. I actually played a tad bit of second where I think they added stealth kills.
