It is the last day of August, which means now is your final chance to pick up some of August 2017's free Games With Gold titles before they return to their normal prices.

On Xbox One, the adorable-looking first-person game Slime Rancher will end its run as a freebie at midnight. Switching to Xbox 360, the third-persons hooter Red Faction: Armageddon is free until the end of the day.
