If there are any legendary old school PC shooters that you've yet to knock off your list, you'd better head to GOG today to check out what the site's got on sale during its "FPS Blast" weekend.

Duke Nukem 3D, XIII, Postal and Postal 2, Far Cry and Far Cry 2, Blood and Blood 2, and Unreal, Unreal 2, Unreal Tournament, and Unreal Tournament 2K4 are all 50 percent off.

That puts each game in the $3-5 range, i.e. cheaper than whatever shitty thing you just ate for breakfast.

These games might as well be called the "Got Blamed For All Kinds of Shit in the '90s Collection," as they're the kinds of titles that were regularly targeted by mom groups and media at every opportunity. In other words, the exact type of game that we love.
