Prototype

Prototype is one of the seven short films comprising the anime adaptation of the Halo universe, Halo Legends.

The story follows a Marine sent to Algolis to destroy a prototype powered armor, but when he arrives, he finds the planet is still inhabited by Humans who are under siege by the Covenant Empire. The suit is their only hope for survival, forcing him to disobey orders and use the suit to help the civilian populace.

Summary
Two Marines take shelter in a forest on an unknown planet, surrounded by their dead comrades. The female marine asks her Sergeant about his codename, "Ghost", while he dispassionately treats her wounds. With her dying words, she asks him, for once in his life, to "be human".

Three years later, the planet Algolis is under attack by the Covenant. The Marines defending UNSC Weapons Research Facility T12A are taking heavy casualties fighting Covenant air and ground forces, trying to buy time for the remaining civilians to evacuate. However, the Hades Corps of UNSC Engineers refuses to retreat until they've destroyed all navigational data and prototype weapons in compliance with the Cole Protocol. As Covenant forces began their final push towards the facility, the Prototype Suit the Marines were sent to destroy flies out of the facility. Piloted by "Ghost", the Prototype Suit single-handedly engages the Covenant forces on the ground and in the air. In the ensuing battle, Ghost is overwhelmed by multiple Elites and Grunts. The suit's shielding system starts to fail and the armor protects him for a short time, until a plasma grenade hits the suit's left arm, severing it and disabling the suit.

As Ghost struggles inside the armor, looking up at the escaping shuttles, he flashes back to the female Marine's death. He admits that, the moment she died in his arms; a part of him was lost and that he had became a ghost, a shadow surrounded by death. The countdown on the suit's HUD finishes, and the suit's system requests a voice command for the self destruct. Ghost turns to face the advancing Covenant for one last glance, and gives the voice command 'BE HUMAN'. The prototype suit explodes in a nuclear detonation, destroying everything within its proximity.

As the evacuees rendezvous with a UNSC Frigate in orbit of Algolis, Ghost's CO reports that the Cole Protocol has been enforced, all navigational data and technology prototypes have been destroyed. He redacts his previous request for Ghost's Court Martial, listing him Missing in Action during heavy combat on Algolis' and informs of their rendezvous with the UNSC Heart of Midlothian.

 * After the first Human Cargo Ship lifts off and is destroyed, the next scene shows a Type-52 Troop Carrier is shown with a Type-25 Assault Gun Carriage in the troop bay. This is inaccurate considering they are usually carried on the underside of Phantoms.
