Halo/Supernatural: The Ancients Revenge
So here is what i was thinking. This takes place in the halo Universe after the events of Halo 4. The UNSC Infinity is on station in orbit of the forerunner sheild world requrim. It carries its usual load of spartan 4's, marines, weaponry, the master cheif, and a new payload. The supernaturals. Their existiance has only recently been discovered. These extradorinary indidviduals have been put to use, including their training onboard the Infinity. You will be either a teenage supernatural, or a who knows how old super natural that looks like a teenager. You have been trained to join the spec ops team of supernaturals aboard the infinity. You are just in time, requrim is about to unleash its full military forces, with covenant reinforcements, and an even more ancient evil than the Forerunners awaken. Are you up to the task?
This would be based around romance, deep story telling, character interaction (yes drama), and of course, since it is halo, fighting aliens and heavy combat.
