The yearly summer sale event is now live for GOG, the DRM-free PC game store. Similar to Steam’s own summer sale, which will likely arrive later this month. GOG promise big discounts on many popular games.

There are 3500+ games on up to 90% off. The theme they’re going for is how ” games connect generations” with sections ranging from old classics from the 80s and 90s all the way to modern hits that have released during the 20s.

Classic titles with discounts include hits like the original Diablo + Hellfire expansion (-20%), Metal Gear (-30%), and Heroes of Might and Magic 3 Complete (-75%). Neither new, but not as old games include Vampire®: The Masquerade – Bloodlines™ (-50%), The Witcher 3: Wild Hunt – Game of the Year Edition (-80%), and Star Wars: Knights of the Old Republic (-65%). Finally there are then the modern games, such as Wasteland 3 – Deluxe Edition (-67%), Cyberpunk 2077 (-50%), and Horizon Zero Dawn™ Complete Edition (-50%).

GOG also announced Alien: Isolation has been added to their massive game library, currently at 75% discount. Along with it is Chorus, which is at 40% discount.

During the summer sale, GOG will also have a 5 free game giveaway throughout. The first, which is available now, is Sanitarium. This will be up for grabs until June 8th 1PM UTC.

The GOG summer sale lasts until June 27th.
