The deal comes a week after the store was down for over eight hours due to the popularity of its last free game giveaway: Grand Theft Auto V. You can grab the game over on its store page. The offer is available until 11AM ET on May 28th, so you have one week to take advantage. Sid Meier’s Civilization VI is available free on the Epic Games Store, meaning you can now claim a free copy that’s yours to keep.
