Of course, no one was prepared for the day when orcs, trolls, and dragons fell from portals in the sky. But the world fought back against the invaders as best it could, with soldiers, tactical weapons, and even some rudimentary magic.

Now a tough, but not-quite-prepared platoon of Marines is trapped on the wrong side of the portals. The enchanting landscape looks like Middle Earth, but - to the dismay of the nerdiest soldiers - is nothing like the Middle Earth they had loved. This so-called fantasy world has much to throw at the soldiers: legendary monsters, extremely rude trees, a mysterious orphan, treacherous mercenaries, and even a cranky, sort of helpful Ranger. As their supplies dwindle and the terrain becomes even more hostile, the squad must also escort a VIP (Very Important Princess). She could be the key to a strategic alliance between the worlds, but only if the Marines can just make it home.
