PlayStation Plus members are running out of time to download August's free games for PS4, PS3, and PS Vita. That's because Sony switches over the free games on the first Tuesday of each month--and Tuesday, September 4 is coming right up. At that point, you'll no longer be able to get August's PS Plus games for free.

The free games in August for PS4 are the open-world crime game Mafia III and the 4v1 multiplayer horror game Dead by Daylight. PS3 owners can download the action-RPG Bound by Flame and the shooter Serious Sam 3: BFE. Those with a PS Vita can get Space Hulk, which takes place in the Warhammer 40,000 universe, and Draw Slasher.
