The Shadow SK sniper with Infestation is a bo7 accounts weapon that can deal serious damage to the head even before Pack-a Punch. Once you stack the correct perks and enhances, PAP2 delivers 119k crits consistently, while PAP3 spikes up to 240k in the right conditions. This translates into a one shot rhythm that lasts well past mid-late rounds without sacrificing fire rate or handling. Here is the complete breakdown, along with a reproducible set-up you can use tonight.

 Context and Core Takeaway

 The numbers prove why the Shadow SK is the best bot lobbies

 Takeaway: Shadow SK is the best sniper amongst all three based on tempo, precision and augment synergy. It is not the fastest gun, but it is faster and more forgiving compared to the other two. And it pairs well with Deadshot and Double Tap.

 Practice:

 Expect to see sustained one-shots in the 45-55-round scaling window as well as fast suppression of elites, bears and HVT (including HVT).

 Damage Logic and Trigger Conditions

 When the right conditions and augments stack up, they can cause big damage.

 Key perk + augment synergy

 - Deadshot Daiquiri (mandatory)

 Major Augment: Dead First. (Double damage when an enemy with full health is headshot by you)

 Why it matters - Your first shot is usually the most crucial. Dead First can turn a standard headshot of 119k into a near-240k.

 Double Tap (highly Recommended)

  - Augment: Double Dealer (every fourth bullet deals bonus/double damage)

 - Meaning in practice: If the fourth shot is aligned through a lane on collats multiple zombies will eat the buff at the same time, clearing the lane instantly.

 - Death Perception (value pick)

 - Trait : Gaining non-crit damage boosts the DPS of your floor and reduces missed crits.

 Triggers and rhythm management

 - Condition A: Full-health + headshot - triggers Dead First double.

 - Condition B : The fourth bullet triggers the Double Dealer.

 - Condition C : Collat alignment. Shared crits along the path.

 This means that, if you start with full-health heads on the first shot and then time your fourth shot to go through a lined up lane at the right moment, you will spread out this 240k spike over multiple bodies.

 ractical Flow & Scenario Tactics

 Transform numbers into a solid plan for all phases.

 Early game (non-PAP).

 What to Do:

 - Deadshot + Death Perception + Double Tap.

 - Develop the habit of opening with headshots that are at full health to trigger Dead First consistently.

 Targets to keep an eye on:

 - As rarity increases, the Crit grows from 1462 to 3216-4000; practice collat lanes by clustered heads.

 Mid-game (PAP1 to PAP2)

 - PAP1:

 You can comfortably control the round pace.

 - Ammo Mod: Napalm burst for DOT and clear pack with burn.

 - PAP2:

 Expect reliable 59k/119k Crits; 119k Carry through collat lanes.

 If you are missing criticals frequently, tighten your positioning. Prioritize a new target with full health, then aim for the fourth shot lane.

 Late game (PAP3 Peak)

 - Peak: ~239,616-240,000 under overlap triggers; 119k common.

 HVT Bear Plan

 - Use Decoys to create a shooting hole.

 Use the fourth shot as a finisher. Often, 3-4 shots are enough.

 - Risk controls:

 - Armor : quickly reach Tier 3; snipers reward stable feet.

 Ammo and mags: While 12 rounds is generous, they go quickly; aim for maximum ammo. Manage your economy. Rotate positions to ensure safe reloading.

 Quick Data & Comparison Chart

 Shadow SK: A quick look at why it is the best choice.

 Takeaway: Shadow SK doesn't mean big numbers, but numbers that you can trigger repeatedly while maintaining the round flow.

 Notes on Advanced Topics and Common Pitfalls

 Small but significant tweaks can improve performance.

 - Pitfall #1: Considering damage barrels a must-have. For this sniper the marginal gains in range/velocity don't outweigh the benefits of mobility and fire speed.

 - Pitfall #2: Chasing criticals without respecting the conditions. Dead First requires full-health and headshots. Choose new targets as your opener.

 - Pitfall 3: Ignoring fourth-shot alignment. Double Dealer transforms the fourth shot into a tactic bullet. Plan lanes to collat.

 - Tips:

 Elemental Pop allows ammo mods to work reliably in all packs (like Napalm).

 - Micro-adjust collats to maintain the reticle's sweep across multiple head heights.

 - Economy: If RNG will not grant PAP Crystals, pay sooner rather than late; round pressure gauges quickly.

 FAQ

 Why am I not able to reach 240k?

 Your fourth shot may not be lined up, or you are not meeting the Dead First requirements. Verify Deadshot Dead First is activated, count shots and align lanes.

 What is the difference between 119k vs 240k?

 119k is a common crit. If you get the Dead First double bonus and/or Double Dealer’s fourth-shot bonuses to overlap, especially on collats, your score will spike up to around 240k.

 Q: Does the fire rate slow down clearing?

 Tempo is extremely workable with LW Trigger attachments and mobility-focused accessories. Shadow SK is faster than the other two snipers and more forgiving when it comes to live rounds.

 Q: I am out of ammunition.

 Collate lanes and decoys to maximize the value per bullet. Elemental Pop can be used to maintain DOT pressure.

 Shadow SK is the best in BO7 Zombies, because it combines three concepts into one lane. Full-health headshots doubles (DeadFirst), fourth-shot bonuses (DoubleDealer), and collat paths. Secure Deadshot and Double Tap. Mirror the build code and the attachments. Then, run the rhythm on full-health headshots, aligning the fourth shot down a lane. You can reliably replicate 119k crits while pushing near-240k spikes. This makes it a main carry for early rounds up to HVT bear melting.
