The Doom Slayer doesn’t need help—but for the rest of us, these expert tips will sharpen your skills, improve survivability, and maximize your efficiency. From resource management to combat mastery, this guide will help you rip and tear through Hell like a true pro.

🔄 1. Use Fodder Enemies Strategically

Fodder enemies like zombies, possessed soldiers, and imps are not just cannon fodder—they’re your lifeline.

• Chainsaw them to restore ammo. It only requires one regenerating fuel bar, so use it often.
• Glory kill them for a burst of health. Avoid killing them accidentally with high-damage weapons like rockets.
• Use the right tools: Stagger with weapons like the Heavy Cannon or Plasma Rifle for easy executions.

---

⛽ 2. Chainsaw Efficiently

Ammo is limited, but the chainsaw is infinite—if used wisely.

• Let the first fuel bar regenerate, and use it on fodder enemies regularly.
• Don’t collect fuel canisters at full bars—save them for when you need to chainsaw a heavy demon (3 bars).
• Know who’s chainsaw-able: Super-heavy enemies like Tyrants or Barons can’t be chainsawed at all.

---

🔥 3. Maximize Flame Belch Usage

The Flame Belch generates armor by setting enemies on fire.

• Use it on groups of enemies for the highest armor return.
• Combo it with grenades or chainsaw kills for armor + health + ammo in one engagement.
• Upgrade its duration and effectiveness with Sentinel Crystals for even better returns.

---

💥 4. Farm Ammo Like a Slayer

Ammo can disappear fast—these tricks keep you locked and loaded.

• Wait for chainsaw fuel regen, then chainsaw fodder enemies mid-fight.
• Use Exploding Pinatas + Regenerating Barrels perks for infinite barrel-based ammo sources.
• Save BFG for extreme emergencies—its ammo is rare, and the Unmaykr shares it.

---

🛠️ 5. Unlock Weapon Masteries Quickly

Mastery upgrades can drastically improve weapon performance.

• Checkpoint reload method: Complete part of a mastery, reload, repeat.
• Use the Ripatorium in the Fortress of Doom for safe practice and progression.
• Target missions where mastery-specific enemies are abundant.

---

🎯 6. Exploit Enemy Weaknesses

Every demon has a counter—use it to control the battlefield.

• Pinkies: Use Blood Punch or flank to hit their exposed tail.
• Pain Elementals: Take them down quickly with the Ballista.
• Doom Hunters: The Microwave Beam is ideal for bypassing shields and locking them down.
• Carcasses: Let them deploy their shields, then pop them with Plasma Rifle to create an explosion.

---

🧠 7. Choose the Best Runes

Runes grant powerful passive boosts—choose wisely.

• Chrono Strike: Slows time while aiming in mid-air—great for precision shots.
• Saving Throw: Grants a second chance when you’re about to die.
• Punch and Reave: Drops extra health from Blood Punch kills—ideal for aggressive play.

---

💎 8. Optimize Sentinel Crystals & Suit Upgrades

Prioritize ammo upgrades early—starting capacity is low.

• Unlock both Sentinel Crystal rooms in the Fortress of Doom.
• Key upgrades:
  • Loot Magnet – Auto-pickup resources.
  • Belch Armor Boost – Increases armor gain from Flame Belch.

For Praetor Suit Upgrades, prioritize:

• Hit and Run (faster movement after Glory Kills)
• Faster Dasher
• Frag Stock Up and Napalm Belch
• Regenerating Barrels and Explosive Pinatas for easy ammo farming

😈 9. Handle Marauders and Archviles Like a Slayer

Marauder

• Stay mid-range: Too close or too far and he defends.
• Watch for the green eye flash—shoot then dodge.
• Use the Super Shotgun + Ballista combo for burst damage.
• Avoid fighting him with other enemies alive—clear the field first.

Archvile

• He summons demons fast—focus him immediately.
• Use the Crucible or BFG if available.
• If not, unload heavy weapons and interrupt his summon as fast as possible.

---

🚪 10. Beat Slayer Gates with Ease

Slayer Gates are optional, but offer great rewards and unlock the Unmaykr.

• Pro tip: Temporarily lower the game’s difficulty before entering a Slayer Gate. Once completed, return to your usual difficulty—no need to replay.
• Use pre-fight prep: Full ammo, full health, and select loadout tweaks can make the difference.
