If unrelenting onslaughts of bad guys who want bad things to happen to you sounds like a good time, then you may be interested in Steam's weekend deal: Serious Sam HD: The First Encounter. The classic shoot-everything-in-sight-'em-up with retooled graphics has been discounted to a very manageable $6.79 from now until Monday on Steam, which comes out to about 817 kills for each copperhead spent. It's a pretty good deal, but be warned: You very well may look to kill anybody wearing a green or blue shirt for the rest of your life.
