Serious Sam HD: The First Encounter only $7.50 on Steam

If you missed your first chance to grab Serious Sam HD: The First Encounter on Steam at a discounted rate, then know that the game is once again on sale from now through March 2. The first episode will set you back a mere $7.50 -- 50 percent off the normal asking price -- leaving vital room in the coffers to snatch up extra rocket and shotgun ammo for the inevitable onslaught.

Trust us, when you've got a pack of wild, headless (yet, somehow, screaming) suicide dudes running toward you, you're going to be glad you spent those extra greenbacks at Uncle Buck's Gun Emporium beforehand. Believe it!
