This week on GOG, add cheap games to your basket at the Harvest Sale.

2019 Game of the Year Disco Elysium is 25 percent off, BattleTech is 50 percent off, Mercenary Collection is 50 percent off, and Life is Strange is 80 percent off. Mercenary Collection is 50 percent off, Life is Strange is 80 percent off, and Serious Sam is free.

You can relieve your exasperation by slaying monster hordes and saving humanity in ancient Egypt; forget for a moment that it's 2020 and enjoy the FPS of 2001 straight out of the year 2001.

If you got a taste of free games with this giveaway, GOG is also giving away Sudden Strike 4. I enjoyed the first campaign of Iron Harvest and have a thing for big, burly mechs. It launches on September 8.

Serious Sam: The First Encounter is free until August 26 at 2 p.m. CST, and the Harvest Sale runs until August 31 at 2 p.m. CST/11 a.m. CST.
