This is a halo trail mod This is a great mod, it puts 2 extra levels onto your base, and it has portals to allot of good sniping places. it has a barecs that has every weapon and a super weapon. it's a needeler that shoots rockets. The new banshees have a cool, green new skin. There is a sniping location that floates in the air that has snipers, health packs, como, and shields. it is a great place to snipe and most people don't know how to get to it. the portal to it is in the cave were the flamethrower would be. keep going in till you see a shield, and go into the crack in the wall and you be there. have fun go here to get the mod
