A gift for my boyfriend. It's the crab-head guy from half life 1. They appeared to have changed him for the most recent version of half life. In the original the heads were a lot smaller and you could tell after you shot them and stared at them that the skull was fully visible through the crab (which I consider far scarier than the newer versions. But then I guess they changed them because it doesn't make too much anatomical sense in the sense of the crabs if they are that small and that empty. )
