I have fond memories of playing the first Serious Sam game. Humor elements like that of Duke Nukem, plus huge hordes of enemies in a gorgeously rendered setting made for a great time. Recently, the Serious Sam games were given the HD makeover, and this weekend, each game is on sale for a whopping 75% off! That's a really... er... serious savings! Definitely worth picking up if you are a fan of fun.
Serious Sam HD 1 - $3.74 Serious Sam HD 2 - $4.99 Serious Sam HD Double Pack - $7.49 Serious Sam HD Gold (including original versions of both games) - $9.99
