DOOM 3 Hints
How can I survive the initial trip across the Mars surface?
1 of 5: Much the same way as you have on these infrequent trips before: run for the opposite airlock and get in quick.
2 of 5: This time things are complicated a little by a cacodemon. Take the time to shoot it down while dodging (or shooting) its fireballs.
3 of 5: Also, the airlock you're going for may seem a little hard to find at first. It's across the surface and to the far right.
4 of 5: There are several air canisters scattered around that you can use to help you stay breathing as you explore the area.
5 of 5: EXTRA: If you're feeling a little daring, jump over the rail next to the balcony at the left end of the area and run down a ravine to find an open crate with ammo and (fortunately) air canisters scattered around it.
