Croteam, the creators of the first-person shooter Serious Sam: The First Encounter on Xbox LIVE® Arcade, will play their game with Xbox LIVE® Gold Members in an Xbox LIVE Game with Developers event. If you're a Gold member (if you're not a Member, upgrade now!) join Croteam and XBLArcade.com on Saturday, March 13, from Noon – 4:00 P.M. ET for some serious (har) action.

Return to the golden age of frantic, non-stop shooting action with Serious Sam's trademark onslaught of enemies rushing towards you at every turn. From the charging Sirian Werebull to the screaming Headless Kamikaze and the multi-story Ugh-Zan, all of the infamous minions of Lord Mental are back as you battle through more than 12 levels of bedlam set against the expansive backdrop of ancient Egypt with every square inch upgraded and reworked to create one of the most visually stunning experiences on Xbox LIVE Arcade.

Developed by Croteam and powered by the next-generation Serious Engine 3, Serious Sam HD features beautifully rendered, high-resolution visuals and lushly redesigned environments to create the most astonishing Serious Sam game ever.

You play as the legendary Sam "Serious" Stone who returns to battle the relentless hordes of Mental's army in glorious high definition on Xbox LIVE Arcade in Serious Sam HD: The First Encounter. Based on the original indie arcade shooter sensation Serious Sam HD: The First Encounter, Serious Sam HD features stunningly redesigned visuals, over-the-top action, and intense online co-op for up to four players.
