It was very detailed too. So I was the Master cheif, running on a sort of barrier or wall, and up too this weird looking AA gun. The Marine was under heavy fire and died, so I “plugged” it in (it had a plug like an xbox mic) and sat in it. I pulled the windshield over and turned it on, like a scissor lift it shot up, and I shot down enemy wraiths coming after allied scorpions, and a few banshees. That’s all I remember, an for some reason I remember it being called “Halo 3.5” or “Halo 1.2” or something like that.
