Good but tough
There is definitely a problem with the attack reload time. In the first level, it takes two shots to kill some guys, which basically means you take about 4-5 damage whenever you see one, which sucks cause you only have like 30 HP to begin with. On the second round I lasted literally about 15 seconds, killing 3 or 4 guys. Anyways, my point is that when I play a game, I use either easy or normal to get the feel of the controls. I only do hard when I know I am good enough to get somewhere. This game seems to be permanently on hard mode.
