In this story Halo finds his way to Equestria when his spaceship crashes on an unknown planet called Alpha he must now save the persons of the planet from the evil Covenant.

Whert peepo have to sae:

But anyways, did I get this right? Halo, the best spartan, pony, dude, dudette and pancake in the worldlaxy (it's galaxy and world, geddit) gets shotted by the evil Cortana who is helping the Covenant becom big and strong? So now he is on a planet and just sexed Fluttershy, and there are no evil humaes, who Halo hates?
This is one intricate plot, can't wait to see what will happen. -Drweegee1337
