Mega-budget as it may be, Final Fantasy 15 has always been content to walk its own road, so it’s not that weird that its latest cross-promo update is with a game that doesn’t exist yet. In a big patch released today, Prince Noctis can stumble into a new adventure with Sarah, protagonist of upcoming mobile RPG Terra Wars. It’s being developed by Mistwalker, a team of ex-Square Enix folks. Those playing FF15’s online multiplayer can now also dress up in Lara Croft’s iconic tomb-delving gear, and listen to some Tomb Raider tracks on the radio in-game. Nifty.
