On second mission. Got into Warthog--which I find extremely difficult to control--and I was stuck about where I was supposed to go. I am in an enclosed outdoor area. There is an internal structure with ramps in a cave, and I went in there, hooked into some terminal, and got a cutscene. I figured that was the point of the cave. Actually, there is a gap that I need to jump with the warthog according to a readthrough so I will try that another day.

Stated Halo CE, got through the first stage. It feels like a fairly typical shooter, very repetitive. I am looking forward to actually landing on "Halo" which I think is pretty gorgeous.
