Here Come the Hacks (HCtH) is a Half-Life 2 Deathmatch mod where an elite squad of G-Men are sent to destroy the Combine's latest invention.
So, I tried to make an evil G-Man. I'd say I succeeded. This will probably be a boss, but it's also something else. Here's the deal: All the developers (those who produce enough content, that is) get custom playermodels, unique to them. The game will check your SteamID if you try to use them, so good luck trying to use these yourselves.
