The Locust Horde invade Halo.

Years have passed since the supposed death of Spartan 117, and the war with the Covenant has finally ended. But Earth is not safe yet, as another space menace has invaded their planet, The Locust Horde (G.O.W). Can the UNSC fight of this new menace without their legendary hero, or will Earth be devoured....

eLITE BACK UP AND locust are smashed. They UNSC will handle them just nicely with convenant and earth weapons. and i think dis is aginst the rule

Just the UNSC, no elites. Just those marines that get in your way during the campaign. Locust Hordes rape and pillage Earth.
