okay so since this is an idea thread...

ACT 1:
you are going into the city to , then you fight your way through the aliens, at teh drop off point using AR, BR, and smgs and spike grenades then you group up with some marines at a nearby command point and use a gauss hog to mow down covies. then banshees go overhead no phantoms because that might be too hard to beat and you shoot them down with gauss hog Then you fight your way up a multi-story buildingto rescue a squad of marines and snipe some covenant and then get airlifted to the tunnel to meet up with the second brother, but you are attacked by a buttload of hunters and must hold them off until the pelican arrives
ACT 2:
you are wounded from the crash so you start at half health and only a little ammo and like 3 or 4 marine teammates wounded. this would force the player to improvise and take cover and conserve ammo (something that real marines have to do) soon you meet up with some other marines. the first objective is to take over a covenant controlled building complex. you are part of the division that goes straight towards it. you are driving a warthog when suddenly your convoy is attacked by heavy banshees only marines are horrible AI so it would be difficult for the player to manage ground forces AND air forces(shoot fuel rods and drop multiple plasma nades [i can lend the tags for that]) only the invinciblemarines on your scorpion survive due to pelicans coming in and saving you. The attack is abandoned and you are airlifted to the tunnel where you meet with the first brother

ACT 3:
you start off in a HEV (Human Entry Vehicle) you experience the drop and hear as some of the squad members die on the way down. Your objective is to board and destroy a covenant ship which is undergoing repairs there is too much AA fire to drop down on top of it. one of the marines is carrying a bomb and you must escort him into the ships engine room where he will plant it, you then have a short time to escape and fly off in banshees towards the tunnel with the brothers, but your teammates are killed by covenant AA in a cinematicand you just barely escape to crash land outside the tunnel with a flamethrower and toast some covies :D. Then the three brothers enter the tunnel to and in the end they win and are flown off in a pelican as the sun sets

THE END :)

keep in mind thats just what i think would be cool, feel free to expand on, remove parts of, or criticise, my idea
