BUILD REPORT
Ghost Protocol Viper
This build weaponizes the Assassin's Smoke Screen and Active Camo to create isolated kill windows on high-value targets — you flank under cloak, pop smoke to break LoS, and burst down isolated runners before they can call for help. Every item choice feeds the core loop: get in unseen, eliminate cleanly, and vanish before the squad collapses on your position.
A
LOADOUT GRADE
RANKED VIABLE
Weapons
Stryder M1T
PRIMARY
At 36 damage per shot and 180 RPM with a 12-round mag, the Stryder M1T is the ideal flanking precision rifle — high per-shot damage means you can drop a target in a tight burst window while under Active Camo's 1.5s disruption timer after the first shot. Its mid-range profile matches the Assassin's engagement envelope: close enough to guarantee hits post-flank, far enough to avoid melee trade risk. Two-tapping a 120 HP target is achievable with precision hits, which is exactly what you need when your cloak window is limited.
Bully SMG
SECONDARY
The Bully SMG at 15 damage and 540 RPM on Heavy Rounds fills the CQB gap when a flank goes loud or a target closes distance. If the Stryder needs a reload mid-engagement, the Bully finishes the job at contact range without requiring precision — critical when the 1.5s cloak disruption window has already burned and you're fighting dirty.
Weapon Mods
CHIP SLOT
See Ya (Superior)
Reloading on an empty mag triggers brief invisibility — this directly complements Active Camo gameplay. After burning your first mag on a high-value target, the reload itself buys a re-cloak window, letting you reposition or break pursuit without burning your Tactical ability again. For a solo flanker, this is a lifeline when the engagement doesn't resolve cleanly.
MAGAZINE SLOT
Hi-Speed Mag (Superior)
Listed at a reported reload speed reduction of ~0.52s and +3 magazine size for the Stryder M1T — sources list these values, unconfirmed in-game. The Stryder's 12-round mag is tight for multi-phase engagements, and faster reloads tighten the window between See Ya's invisibility trigger and re-engagement, keeping your kill tempo high.
BARREL SLOT
Pinpoint Barrel (Superior)
Greatly increases stability and range on the Stryder M1T. Flanking shots are often taken from awkward angles at speed — extra stability means your first two shots land clean even if you're slightly off a full ADS settle, and the range extension pushes your effective envelope further without compromising the mid-range profile.
CHIP SLOT (BULLY SMG)
Cloudborn (Standard)
While in smoke — which you will be constantly via Smoke Screen and Shadow Dive — this mod increases stability, accuracy, handling, and movement speed on the Bully SMG. Your CQB backup becomes a smoke-enhanced closer, turning every Smoke Field into a stat buff zone for your secondary.
OPTIC SLOT
Vigilant Lens (Superior)
Listed at ads_speed -0.09s and ads_spread -0.33 — sources list these values. Faster ADS speed is critical for the Assassin's burst-window shooting style: you break cloak on first shot, so every millisecond of ADS time saved before that shot fires is free damage before the target reacts. The spread reduction tightens the Stryder's already-capable precision profile.
Shell Cores
Shadow Strike (Prestige, Passive, Meta Rating: S)
PASSIVE
Your Utility Knife deals greatly increased damage when attacking from invisibility — this is the Assassin's signature assassination tool. Combined with Active Camo, a knife opener from full cloak followed by a Stryder burst can eliminate a target before they process what happened. S-tier meta rating makes this the non-negotiable anchor of the build.
Safe Landings (Deluxe, Passive, Meta Rating: A)
PASSIVE
Shadow Dive knocks nearby hostiles away on landing and creates a longer-lasting smoke field. This directly extends the smoke coverage window when you use Shadow Dive to close on a target — the knockback creates spacing for your burst, and the longer smoke duration gives you more time inside Cloudborn's buff window. A-tier rated and directly amplifies both offensive and defensive flanking mechanics.
Guerrilla (Superior, Passive, Meta Rating: B)
PASSIVE
Active Camo and Shadow Dive recharge more quickly while in smoke. Because you'll constantly be generating smoke fields via Smoke Screen, Shadow Dive, and the extended fields from Safe Landings, your ability uptime compounds: more smoke means faster recharge means more cloak means more Shadow Strike opportunities. This creates a self-reinforcing loop that defines the build's pacing.
Implants
HEAD
Energy Harvesting V4 (Superior)
Firewall: -5, Tactical Recovery: 40%
40% Tactical Recovery directly feeds Active Camo uptime — the Assassin lives and dies by how often they can re-cloak. The Firewall trade-off is minor for a shell that avoids sustained firefights entirely. The passive 'Walk it Off' also provides mid-run status cleanse for Toxin or Bleed that could interrupt a flank approach.
TORSO
Knife Fight V4 (Superior)
Hardware: -10, Melee Damage: 50, Fall Resistance: 20%
50 Melee Damage directly amplifies Shadow Strike (Prestige core), which already grants massive bonus damage on knife attacks from invisibility. This implant makes the knife opener from cloak potentially one-shotting or critically wounding before a single shot is fired. Fall Resistance synergizes with Shadow Dive's aerial approach vectors. Hardware loss is acceptable — you shouldn't be taking sustained hits in this playstyle.
LEGS
Graceful Landings V4 (Superior)
Melee Damage: 20, Agility: 20, Fall Resistance: 50%
Stacks an additional 20 Melee Damage on top of Knife Fight V4's 50, creating a combined +70 Melee Damage modifier that makes Shadow Strike's invisibility knife opener devastating. Agility 20 improves flanking movement speed and repositioning between engagements. The Frenzy Matrix passive — defeating a hostile increases tactical recharge rate and sprint speed — directly chains into the Guerrilla core's smoke-based ability recharge loop, compounding your kill-to-cloak tempo.

Assassin Cradle Build — Season 2 Stat Plan

Free respec · resets each season
Invest primarily in Strength and Recharge tracks to maximize the knife-from-cloak kill spike and ability uptime, with secondary points in Dexterity for flanking mobility.
STRENGTH TRACK
14 ENERGY
PERK · Leech
Reaching Leech at 14 Energy picks up Finisher Protection at 6 and Close & Personal at 11 along the way — all three perks serve the knife-from-invisibility playstyle. Leech restoring health on knife attacks creates sustain during the knife opener, Finisher Protection reduces risk during finisher animations, and Close & Personal reduces heat from melee, keeping your heat profile clean for sustained ability use. All values unconfirmed per source markers.
RECHARGE TRACK
14 ENERGY
PERK · Lethal AMP
Lethal AMP at 14 Energy grants Tactical energy on Runner downs and Prime energy on eliminations — this directly feeds Active Camo and Smoke Screen recharge off kills, which is exactly what a high-value target elimination build needs. Head Start at 4 and Primed at 10 give you partial ability charges at run start, meaning your very first engagement can begin cloaked. All values unconfirmed per source markers.
DEXTERITY TRACK
14 ENERGY
PERK · Full Throttle
Full Throttle at 14 Energy gives Cardio Kick effects at run start — a free movement speed buff at spawn accelerates your flanking route setup before the lobby stabilizes. Slider at 11 reduces heat from sprint-sliding, keeping your heat profile low when you're closing distance aggressively. Loot Siphon at 5 adds Tactical energy from container opens, useful for pre-engagement cloak topping. All values unconfirmed per source markers.
STRENGTHS
+Compounding cloak uptime via Guerrilla core + Energy Harvesting V4's 40% Tactical Recovery + Lethal AMP Cradle perk creates near-continuous Active Camo cycling on active engagements
+Shadow Strike (S-tier core) + Knife Fight V4 (Melee Damage: 50) + Graceful Landings V4 (Melee Damage: 20) stacks a combined +70 Melee Damage on invisibility knife openers — burst assassination potential is extremely high
+See Ya chip on the Stryder M1T provides a mid-engagement re-cloak on empty reload, giving the build two independent invisibility vectors without spending Tactical ability
WEAKNESSES
The Assassin's base 120 HP with no shield and Hardware sacrifice across Knife Fight V4 (-10) makes any sustained firefight or team collapse scenario very punishing — this build has zero margin for prolonged exchanges
Stryder M1T's 12-round magazine (even with Hi-Speed Mag's reported +3) and 180 RPM means multi-target engagements burn resources fast — solo play against grouped targets is a hard counter to this configuration
RANKED NOTE
This is a casual-optimized build with no ranked constraints — it can absolutely function in ranked environments (Assassin is Solo A-rated), but ranked optimization would likely trim Dexterity Cradle investment in favor of deeper Resistance or Endurance for sustained run survivability.
⬢ Build Analysis
Here's the honest read: Ghost Protocol Viper is built around a single, devastating interaction — Shadow Strike (S-tier, confirmed meta) plus the stacked +70 Melee Damage from Knife Fight V4 and Graceful Landings V4 makes your invisibility knife opener hit like a freight shell. You're not sneaking around hoping to chip damage. You're cloaking, diving in via Shadow Dive with Safe Landings' extended smoke and knockback to create spacing, opening with a knife hit that should critically wound or down a 120 HP target outright, then finishing with the Stryder M1T's 36-damage precision shots inside the 1.5s disruption window. The Guerrilla core means every smoke field you land — and Safe Landings makes them last longer — accelerates your next cloak recharge, and Energy Harvesting V4's 40% Tactical Recovery compounds that. See Ya on the Stryder is the sleeper pick here: empty-mag invisibility is a third repositioning tool the enemy can't predict. The Bully SMG with Cloudborn Standard means your smoke fields actively buff your CQB closer. This isn't a one-trick — it's a loop. Flank. Knife. Burst. Smoke. Vanish. Repeat.
