So Ravenholm is straight out of Resident Evil. They might not be actual zombies, but they’re no so different. And then there’s The Predator who jumps around the rooftops and climbs drainpipes. Oh, and the harder versions of the headcrabs who poison you as well as jump on your face.
I didn’t really like Ravenholm that much. Nothing about it seemed like Half-Life to me at all, and the loon from the church just detracted further. After that, it was onto the mines, which were full of headcrabs and poisonous headcrabs, and then it was out into the open and I got myself a car (of sorts) with a gun on it.
