In single player, how can I get the two beasties are they unbeatable. I try dodging in and outof the columns but still get beaten, is there a cheat for this part if so how and where do I apply it
Try moving away from the action to take a rest, and find a medkit or two. Also, you can attack them from a distance (use ranged weapons). You'll only want to get up close if you are very well at dodging their attacks.
