H40 TIPS

A few tips when playing the character

• Pickpocket
  • Grants near infinite ammo. Note that you just have to land the killing blow via direct or DoT attack. These can be either melee, or range kills. 
  • You should NEVER pick up ammo 95-99% of the time. The only reason I pick it up is if I'm completely out, and trying to get a quick kill to get me another 20-25 ammo back. 

• Weapon Handling
  • Needle Pistol 
    • For some reason, sprint+sliding+weapon special changes the needle type from yellow to blue and vice versa faster. 
      • I'm not sure if this is a glitch but as of 1/2/26 this is how it works.
  • Bonesaw
    • Toxin Coating
      • Carapace, Bosses
        • Purple
      • Everything Else
        • Yellow
  • Recommended Mods
    • "A la Mode" (aka Needle Dial)
      • A massive QoL change that will give you color coded icons for Scum weapons
    • "Stimm Countdown"
      • A massive QoL to the menu we currently have showing CD on Stimm

• Needle Count Recommendations for TtK, DoT, Threat Assessment
  • One important note: this isn't a minimum shot/breakpoint calculation
    • This is to maximize TtK (Time to Kill), DoT (Damage over Time), and how much of a threat the enemy poses to you
  • Max Needles = 5
    • After this it's diminishing/non-existent returns
  • Enemy:
    • Mutant = 0-1
    • Snipers = 1
    • Hounds = 1-3 contingent on immediate threat
    • Flamers = 1-3 contingent on immediate threat
    • Bombers = 1-3 contingent on immediate threat
    • Trappers = 2
    • Gunners = 2
    • Reapers = 4
    • Ragers = 2-4 contingent on immediate threat
      • If Rager mob - just spam fire to DoT as many as possible
    • Maulers = 2-4 contingent on immediate threat
      • If Mauler mob - just spam fire to DoT as many as possible
    • Crushers 3-5 contingent on immediate threat
      • If Crusher mob - just spam fire to DoT as many as possible
    • Bosses = 5
      • After attack, shield, or chaotic sequence
        • Shoot 1-3 to refresh or replenish stack

• Positioning - Zig-Zagging from Frontlining to Backlining
  • First off, you will want to make a habit of running with your Needle Pistol out, and reloading it.
    • Sprint & Slide
    • This will maximize Stripped Down making you immune to ranged fire while traversing
  • You will constantly be zig-zaging back and forth of pushing Gunner lines, hitting DoT, pulling aggro, and retreating to the backline
    • Run'N'Gun will help with killing Specials & Elites

• Boss Fights
  • Switch Needle Pistol to Yellow
  • Shoot 5 times
  • Switch to Bonesaw > Switch to Purple
    • Melee
  • After attack, shield, or chaotic sequence
  • Switch back to Needle
    • Shoot 1-4 times to refresh stacks
  • Switch back to melee
  • Repeat

•  Here Comes the Boom
  • Good rule of thumb: 15-20 Crushers, Maulers, Ragers, and/or Bulwarks
  • If you are the only one picking up nades then you can be a bit more trigger happy

• Horde Clear
  • Bonesaw is solid all-around weapon and has decent trash horde clear
  • If need be, switch Needle Pistol to blue and fire at every 2-4 enemies and this should cause enough explosions to cull the herd
    • Then finish with Bonesaw

• Clutch Revives
  • IF Specials & Elites - Shoot Yellow needles at all to kill
  • IF Trash - follow "Horde Clear" above
  • IF Horde - 
    • Rocket
    • Stimm Supply > explosion > then revive while enemies are staggered
