The Ballistic Force Crossbow, or BFC, is Doom: The Dark Ages' answer to the BFG (basically the same thing). It’s devastating, explosive, and able to wipe entire rooms off the map with one shot. Just like the classics, you won’t get much ammo for it, so every pull of the trigger better count.
Here’s everything you need to know about unlocking, using, and getting the most out of the BFC.

What is the Ballistic Force Crossbow (BFC AKA the BFG)?
The BFC is a heavy energy weapon that deals massive AoE (area of effect) damage. It’s designed for crowd clearing, emergency wipes, and boss bursts. One well-placed bolt can erase an entire wave of demons, but you probably won’t have more than a few shots at a time.
It functions as a late-game power weapon, not a regular part of your loadout cycle. Use it when you’re backed into a corner or need to turn the tide of a losing fight fast.
How to Unlock this BFG
You get the Ballistic Force Crossbow in Chapter 14, during the mission involving the Spire of Nerathul. It’s a guaranteed story unlock, so you can’t miss it. After that, you’ll be able to quick-swap to it like any other weapon.
Why It’s Called the BFG Replacement
Massive burst damage
Can clear entire groups of enemies
Limited ammo makes it a “save it for the right moment” weapon
Feels like a reward for surviving this far into the game
You won’t be using it constantly, but when you do, it’s one of the most satisfying weapons in the entire campaign.
BFG Ammo Tips
Very limited supply… You’ll rarely find more than 1 or 2 charges at a time
Prioritize using it during Gore Nest waves or boss phase transitions
Don’t waste it on single enemies unless they’re buffed or part of a challenge
If enemies are grouped near hazards or explosives, let the BFC multiply the chaos
Final Blurb
The Ballistic Force Crossbow is pure destruction, but you’ll need to treat it like gold. It’s not just the strongest weapon in Doom: The Dark Ages, it’s one of the most strategically important. Use it smart, save it for the worst moments, and you’ll always be glad you had it in your back pocket.
