The chance to save a bundle of cash on PC and Mac downloads this weekend has been flying in from all angles. Hamza's already let us know about Amazon.com's crazy End of February sale and BioShock Infinite's crazy pre-order deals; Jordan's mentioned Steam's free weekends for Call of Duty: Black Ops II multiplayer and Gratuitous Space Battles, but there's still more ways to save.
GOG.com is running a 60% off promo on Apogee titles, including all the classic Duke Nukem games from the early '90s along with other cult classics like Blake Stone, Shadow Warrior, and a personal favourite, Rise of the Triad. Considering the remake/reboot of Apogee's over the top shooter is on the way, now's a great time to check out the original.
GamersGate has been running a Nordic Games Week promo, so check back each day for new daily deals. Right now, the complete Painkiller and Gothic packs are 75% off. Green Man Gaming also has another weekend offer, this time it's 40% of the challenging platformer Dustforce which also has its brilliant soundtrack included. We've covered a lot of deals today but if you find another great weekend PC and Mac download deal, please post it in the comments.
