After playing the demo I found my self not enjoying combat at all. The guns feel extremely underpowered, you need like 30 bullets from pistol to kill 1 guy. Guns feel like nerf blasters. The gore was better in the first game, right now it looks like crabs, there were quite a few times when I saw crabs but it turned out to be killed chickens.
Melee combat isn't that bad, but it isn't good either, it doesn't really require any skill, you just go up to a group of enemies and spam attack.
