Doom (2016) delivers a satisfying arsenal that feels powerful and purposeful. Here are the top weapons ranked not just by firepower, but by versatility and effectiveness in both combat and exploration:

1. Super Shotgun 
   The ultimate demon-slayer at close range. Its double-barrel burst can eliminate Imps, Pinkies, and even Cacodemons in one blast. Perfect for aggressive players who favor face-to-face encounters.

   • Tip: Pair with the "Savage" rune for devastating Glory Kill chains.

2. Gauss Cannon
   A precision weapon that doubles as a sniper rifle and boss destroyer. The Siege Mode mod turns it into a high-risk, high-reward cannon with splash damage.

   • Tip: Use during vertical arena fights to pick off Hell Knights and Revenants from ledges.

3. Rocket Launcher
   Reliable and destructive. The Lock-On Burst mod makes it ideal for fast-moving targets like Mancubi or Summoners.

   • Tip: Fire at enemy clusters, then follow up with a Super Shotgun to finish survivors.

4. Heavy Assault Rifle
   Great for mid-range. Its Micro Missiles mod turns it into a fast, splash-damage support weapon.

   • Tip: Works well against flying enemies—burst missiles before switching to hitscan weapons.

5. Chainsaw
   Technically a tool, but essential for resource farming. A single kill refills ammo and gives a breather during tough waves.

   • Tip: Save fuel for big enemies like Hell Knights to gain maximum resources.

The Praetor Suit upgrades make a significant difference in how you traverse environments and survive ambushes. Here’s how to get the most value:

1. Start with Area-Scanning Technology
   Reveals secrets and collectible markers on the map. Helps you find hidden items and rooms faster.

2. Follow up with Environmental Resistance
   Reduces damage from hazards like toxic barrels, lava, and explosive traps—especially useful in the Foundry and Hell levels.

3. Invest in Dexterity next
   Increases weapon swap speed and grab ledge speeds. You’ll be more agile during platforming and arena movement.

4. Leave Equipment System for last
   Boosts grenade recharge and other support tools. Useful, but secondary to movement and survival.

Tip: Explore every optional area to find Elite Guards and collect tokens faster.

Classic maps offer a nostalgic reward. Each level features a lever that unlocks a hidden room with retro textures:

• Mission 1 – The UAC : Find the lever behind a locked gate near the second collectible. Classic level features E1M1 homage.

• Mission 2 – Know Your Enemy : Near the Elite Guard room—hidden lever opens the retro corridor.

• Mission 4 – Argent Facility : Classic lever behind barrels near a power core chamber.

• Mission 6 – Kadingir Sanctum : Jump from a boost pad into a ledge tunnel to reach the lever.

• Mission 9 – Lazarus Labs : Pull the lever in the surgical room to access E2M3-style map.

• Mission 11 – The Necropolis : Found just after defeating the twin Barons of Hell.

• Mission 13 – Argent D’Nur : Near the final arena, behind a statue pillar.

Tip: Classic maps must be finished to count toward achievement progression.

Runes enhance gameplay dramatically, and the right combination can mean the difference between surviving and restarting:

• Savage + Dazed and Confused
  Glory Kills are faster, and enemies stay staggered longer. Ideal for crowd control and arena pacing.

• Equipment Power + Armored Offensive
  Boosts equipment recharge and rewards Glory Kills with armor. Great for nightmare difficulty.

• Seek and Destroy + Blood Fueled
  Increases stagger range and grants speed boost after Glory Kills. Keep moving, keep killing.

• In-Flight Mobility + Air Control
  Crucial for vertical platforming stages like Mission 5 or the Rune Trials involving mid-air targets.

Tip: Experiment with different combos based on level design. Rune switching doesn’t require a menu penalty

Going for 100% on consoles or Steam? These pointers will help:

• Finish the Campaign on Nightmare
  Unlocks Ultra-Nightmare mode and the “IDKFA” trophy.

• Collect All Runes, Upgrades, and Classic Levels
  Earns the "Argent Fiend" and "Historian" achievements.

• Complete Every Rune Trial with Max Score
  Unlocks mastery for every rune, allowing full stacking potential.

• Farm Combat Challenges
  Each mission includes bonus goals—headshot counts, Glory Kill types, and weapon mastery. These count toward progress.

• Explore Bonus Content
  After finishing, return to missions via level select to grab missed secrets. Classic maps and Elite Guards must be collected in the same session.

Tip: Some trophies are tied to specific actions—like killing a Baron of Hell with the Chainsaw. Review trophy descriptions closely before your final playthrough.
