A new trailer for Monolith Soft's X was shown during Nintendo's E3 2013 Direct stream, showcasing humongous swords and even bigger mechs. This is the studio's follow-up to Xenoblade Chronicles, which we've talked about a bit in the past, and is set to release sometime in 2014.
While the basic gameplay looks very similar to that of Xenoblade, you can also pilot giant mechs called Dolls, which can not only fly, but also transform into badass tanks. There's been no confirmation yet as to whether or not this is an MMO or a multiplayer JRPG, but we're almost certain it has an online cooperative component. Stay tuned for more info.
