New A.I Survival Custom Game: The Covenant Assault

The Covenant Assault is a 4-player wave-based survival minigame where 4 players are tasked with defending a UNSC outpost from oncoming Covenant forces. This map is similar in setup to the Night of the Mantis. Take on Ghosts, Wraiths, Jackal Snipers and even Banshees in your battle. Each enemy is worth points and points can be used to buy sets of weapons from the Armory that are progressively more powerful to compensate for your battles against the more powerful foes. The map has 4 accompanying game modes or difficulties: Easy, Normal, Heroic, and Legendary. All necessary links are in the description of the YouTube showcase video here.
Enjoy and feedback would be awesome.
