That's the planet upon which the Gears of War games are set, right? I never thought the story of those games was worth getting in to. Anyway, I'm guessing the Locust weapons won't be able to penetrate Mjolnir armour. The Spartans are also much more mobile and energetic. As long as they have enough ammo and other supplies, the Spartans will slaughter left right and centre. It depends on the numbers though.
