The folks over at GOG have just launched their “SummerGaming Sale” and they’re kicking things off by giving away a free copy of Xenonauts, a turn-based strategy game inspired by the classic X-COM series. The free download includes versions for macOS, Windows, and Linux and, like all GOG-distributed games, is DRM-free. The GOG sale is on until June 18th, but the free Xenonauts offer is only good for the next 48 hours.
Shadow Warrior, the classic 1997 3D Realms first-person shooter, is available for free from GOG. The game runs on both Windows and macOS, and includes both expansion packs, Twin Dragon and Wanton Destruction, as well as the game’s soundtrack. You can also pick up the remastered “Redux” version of the game from Steam for just $0.99 as part of the 2017 Summer Sale. So if you’re itching for some classic FPS gaming, act fast!
