Zombies.
They had longer claws in the game, the right arm looks a bit funny and I think the body is too wide compared to the rest. I think the head crab looks funny somehow... don't really know how though :/ bit of an overly simplistic background, would have liked something better then a grey cuboid with a light in the corner. It would have taken more work I know but a little more detail on the room would have been nice. 6.5/10
And by the way people judging by the smiley at the end of his review "Infected Rabbit" was joking. Please learn to spot sarcasm in its many forms.
