Steam News has word that they are now selling four-packs for Serious Sam HD: The First Encounter. Word is: "Serious Sam HD: The First Encounter is now offering a four-pack so if you've been itching to play with your friends this is the best way to do it as you can gift out your extra copies to your buddies!" Of course you can't actually play with your friends, since this Serious Sam remake doesn't support multiplayer at this time, but that it being worked on for a future patch.
