Two classics from the old Doom series make a return in this campaign. The Chainsaw and BFG are instant-kill weapons, but their ammunition is limited. Use wisely during the big arena battles and always keep an eye out for fuel tanks and BFG ammo. Both are selected with a special key/button, making them easily accessible.

There have been reports of this item being seen at the Argent Facility, though there are no known uses for it. Security personnel have been made aware that this item has likely been smuggled onto Mars, and have been directed to confiscate it immediately. As there are no practical uses for it, it must be assumed that this item should be considered a black market enthusiast’s weapon.
A powerful close-range weapon that one-shots weak enemies and finishes off the elite ones. Enemies shower ammunition upon death. Using the Chainsaw requires fuel—the bigger the demon, the more you need. Fuel tanks are found sparingly around the maps, so conserve when possible. With that said, it’s a waste to not use it. Try not to leave a big battle with maximum fuel or you may regret not using it when you find your next fuel tank.
BFG-9000
Locations Found Advanced Research Complex
Ammo 3 (unaffected by upgrades)
The theoretical design for the BFG-9000 was first put forward by the R&D department in the Advanced Research Complex, and the concept was later given its own funding program. The BFG Division was formed to develop a working design. Several prototype weapons have since been made.
The prototypes never went into full production due to numerous testing accidents and the deadly radiation spikes produced. Previous versions of the weapon had slightly different energy patterns to the current generation. Some released solitary Argent spheres that unleashed a deadly wave upon impact, others formed an Argent laser that cut through anything in its path. The current prototype, the BFG-9000, creates Argent streams that seek out targets and boils them alive.
This is a powerful weapon that delivers streams of supercharged Argent plasma to multiple targets and is somewhat self-guiding. Just getting the shot near a target zaps it and any other nearby demons along the way. The most effective BFG shot is one that travels through the world for a long time. Try to thread it through a group rather than aiming at a single, nearby target.
