Dress like Lara Croft in Lightning Returns: Final Fantasy 13
Crossover costume DLC is no new thing - you can dress as a knight from Dragon Age in Mass Effect 3, for example -- and Square Enix is playing that game with Lightning Returns: Final Fantasy 13, for which you can obtain Lara Croft's outfit from Tomb Raider 2013.
As you can see in the vid, this pack gets you Lara's clothes, her axe, a riot shield and a bunch of dirt. Lightning Returns is out next week for PS3 and Xbox 360.
