i used the smartgun to get through the whole wave of aliens and then the 2 big mamas. If you use it accuractly rather than just blasting and wasting ammo, you can finish them all off and still have about 100 or so ammo to spare.
I found that walking up to the praetorians (or whatever they're called) to a certain point will only make one of them run at you. I just ran backwards and reloaded when one was dead, then attacked the other.
