Random not-so-spoiling question

Anyone know if we'll be able to walk along the Martian Surface???

I know the DooM Bible mentiones massive canyons connecting bases and all.

O, and it looks like my "Mars City" call from an earlier post was correct after all!!! But is it really a "city"??

(And should I shut up cause i'll find out soon)

Yes, the suit you get ingame has an air supply for just that reason, and of course to make things interesting it runs out of air as you go around and you have to find convienently placed air canisters to restock it.

edit: oh, and I hear the dust/atmosphere of it is amazing.
