I used to think Bungie were Exaggerating on how much content was cut from Halo 2, But HOLY FUCK!
First image is from the ARK from Halo 2 which we later see in Halo 3 Mid Game
Second is of the cut warthog run as we know it
The third is how halo 2 was actually supposed to look like, with high tech dynamic lighting, but the og Xbox couldn't handle it. I almost thought that it was halo 3 for a moment
