See if you can base it more on EDV. The car in the is siginificantly more awesome, and even has a gun already! It's like the work is already done, we just need sprites and offsets! Sorta!

I just have to say that this is the first topic that has two pages
But the EDV tank is like, huge. I was thinking about things to scale.
And, if the HALO mod would be mainly actors and weapons, then why would it be so hard? I little bit of work now and then, and you've got a hit.
If the sprited actors were anything better than Regiment56 it'd be somewhat popular. Just 'cause a game's 3D doesn't mean it can't be smashed down repeatedly into a 2D one.
