Steam is the online delivery and anti-piracy client that Valve used to distribute Half-Life 2. Even people who bought the retail version of HL2 had to create a Steam account and verify their copy of the game. Valve cracked down on pirated copies, banning some 50,000 illicit accounts.

Steam has been a bit controversial, however. Many gamers complain about having to log in to Steam every time they want to play, but I personally love the system. Valve has released new content, patches, upgrades, models, and maps nearly every week since the game was released, and even provided gamers with the the wonderful surprise of an HL2 Deathmatch game.

Posing notes: Again, Frohman is the only ragdoll, the others are live, in-game characters. As the cops rushed in and the citizens started running around, I'd switch off the AI, which would freeze everyone in their tracks. Then I'd move around, get the shots I needed, and pose Frohman. Turning AI on again, everyone would come to life, and change positions, and I'd freeze them again.
