With all the changes that id Software has made with DOOM Eternal, it’s much easier to run out of ammo than before. The important thing to remember is that the Chainsaw now passively recharges. Use it on smaller foes to instantly receive ammo. However, there’s another way to get ammo pickups besides just scanning the level.
Take the Praetor Suit upgrades for nullifying damage from explosive barrels. Then take the upgrades that cause ammo to drop from explosive barrels and having the barrels respawn after some time. Whenever you’re low on ammo or need a top-up between fights, shoot any barrels twice and pick up the ammo that drops.

How to Beat All Bosses
There are a fair few boss fights and while some might be a handful, they’re fairly easy with enough practice. Check out the video below for a full walkthrough of each fight or scan for some tips below:
- Doom Hunter – Disable its shield before attacking. Focus on disconnecting its upper body from its lower. Two more Doom Hunters will spawn after the first is killed
- Marauder – Must be in medium range. Attack with a Super Shotgun and immediately switch to Arbalest for additional damage.
- The Gladiator – Focus on staggering at first and keep your distance. Watch out for its melee attacks in second phase
- Khan Maykr – Be careful of Khan Maykr’s laser from the skies – keep a good enough distance so you can see where it’s moving. Take down her shield and use the Meat Hook on the Super Shotgun to Blood Punch her. Be careful when she lights the ground on fire.
- Icon of Sin – You have unlimited Crucible and Blood Punch pick-ups here so go wild. Target the Icon of Sin’s armor first. In the next phase, target its body parts. Use the BFG to accelerate the process. Do not shoot any part that’s already been destroyed as it will deal no damage.
