Summer starts to draw to a close, but the weekend PC deals live on. Steam has a pair of weekend promos for us; first up is the arena shooter Nexuiz, which is free to play all weekend and reduced in price by 75% to celebrate its integration with the Steam Workshop. Also on offer is a selection of titles by publisher Kalypso, including Tropico 4 and Jagged Alliance - Back In Action.
GamersGate is into the second week of its summer sale, this week focusing on action titles. There's daily deals to be had, so at the time of writing you can get Duke Nukem Forever, Just Cause 2, Nuclear Dawn, and Saints Row: The Third for 75% off.
Meanwhile over on GOG.com, you can buy the likes of Worms United, Cossacks Anthology and Superfrog for 50% off in the Special Summer Promotion. Elsewhere, Amazon.com has reductions on weapons and items for the free-to-play War Inc. Battle Zone. As always, if you find a good weekend PC deal, post it in the comments below.
