Civilization 5 is free for a limited time for those who purchase its Gods and Kings expansion on Onlive before Tuesday next week.
Purchase the add-on and you'll be given a PlayPass for unlimited access to the parent game. Ordinarily Civilization 5 and its expansion are $29.99 each, effectively making the bundle half off.
Onlive confirmed to us that the deal extends to the UK, where both Civilization 5 and the Gods and Kings expansion will be available 22nd June at 12:01 am BST.
"If you've never played a Civ game before, this is the place to start," said Quentin Smith, who awarded the game an 8/10 in his Civilization 5 review.
However, he wasn't so keen on the Gods and Kings expansion. "Civilization 5: Gods & Kings isn't that good," he wrote in his recent appraisal. "In a series that's always had a certain pride to it, what you're paying for here, really, is a renewed addiction and precious little else." That addiction was still enough for him to give the game a 7/10, though.
Still, it sounds like it's worth checking out for free.
