Steam has to be one of the best places on the web to grab discounted games. Previously, Serious Sam HD: The First Encounter was discounted on Steam but  a lot of users where just to slow to grab the deal, luckily Valve has again offered this discount until March 2nd.

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.
