7. Cerebral Bore

Turok 2

The Cerebral Bore is easily the most memorable part of the Turok series, which turned out to be quite forgettable despite combining first-person shooting with dinosaurs. Fucking that up was quite a feat, but at least we'll always remember this weapon.

It launched a tiny parasite that burrowed into enemies' heads and caused their grey matter to splatter all over the walls. It was an unprecedented level of gore for a shooter at the time, and it made us positively wet in the pants. We're sure we developed no small number of psychological issues due to this, but we've no doubt it was worth it.
