EA has made Battlefield 3 free on Origin between now and 3rd June as part of its "On the House" promotion.
It's usually priced at $19.99 (about £15).
Previous freebies in the promo have included Dead Space and Plants vs. Zombies: Game of the Year Edition.
"We're gamers, too," EA explained when it launched the promo in March for Dead Space. "We appreciate you making Origin your gaming home... and besides, who doesn't like free stuff?"
