You are about to create the most ridiculously powerful Zombies loadout for Black Ops 7: The XR3 Ion Sniper. It crits, charges three shots per shot and can reach nearly 300,000.000 damage per second when upgraded with the appropriate elemental. Why should you care about this? Why should you care cod bo7 bot lobby?

 

 What does it mean in game? If you can tolerate the quirky charge shot, and slightly unpractical base, you will get a powerful sniper. It will collateralize lines of zombies and wipe out Zersa within seconds.

 

 Why bo7 accounts XR3 ION Ion is broken Right Now

 - Conclusion: XR3 Ion currently has the highest DPS of all zombies in BO7.

 

 - Statistics to back it up:

 

 - The highest rarity of crits is 38, 000 crits for each projectile.

 

 The weapon fires three projectiles with each charge. This is equivalent to 114,000 per trigger pull.

 

 - Taking into account the fire rate you can achieve 196,000 DPS for crit chains.

 

 With Napalm applied (elemental), elemental damage increases per shot to 57,000. This brings the total DPS up to 294,000.

 

 - If your aim is on critical zones, and you keep a constant charge cadence for bosses or armored Zombies, they will disappear faster than with M2 or Ray Gun.

 

 The Catch - Practicality vs. power

 - Compared to other snipers: XR3 does more damage, but is less useful at base because of the charge delay, ADS drag or ammo throughput.

 

 It's not your imagination if you notice a stutter in the charge or a drop in damage at distance. The bullet velocity and damage range are key factors.

 

 - If you are struggling before Pack-a Punch, use box hits and early salvage to boost your upgrades. The weapon will wake up after the synergy of perk and Pack-a Punch.

 

 Modifications: Ammo Mod, Perks Mod, Attachments Mod, and Step-by step Build

 - Optics:

 

 Kepler T Range Holo: keep your FOV manageable with out bulky scopes. If you want a clear view, then this is the right choice. You don't need it but it helps you to find your target.

 

 - Barrel:

 

 - LTI Infinity (long bar): prioritise damage range in order to reduce drop off.

 

 Alternative: Hybrid barrel to combine damage range with bullet velocity, if you see mid-range falloff.

 

 - Underbarrel/Handguard:

 

 - Advanced step handguards : improves hipfire, strafe and aim-walking handling.

 

 - Magazine:

 

 - The extended 21-round magazine: Pick it despite the current bug with Pack-a Punch (magnification is reduced from 21 to 14 when PaP is applied). For now, you should plan your ammunition carefully.

 

 Rear Grip

 

 - L9 Grip Vertigo: horizontal recoil and stabilization to make multi-crit chains more steady.

 

 - Stock:

 

 - Mobility stock: improves hipfire and movement to retain the crit tracking when charging.

 

 - Laser:

 

 IMW Instinct : ADS is faster. XR3 gains a lot from this, because ADS + Charge can be a bit sluggish.

 

 - Ammo Mod:

 

 - Rapid Fire Quick Charging: This reduces the charge time while increasing ROF. It is at this point that XR3 bursts become ridiculous.

 

 

 

 - Perk Synergy:

 

 - Double tap: increases firing rate. Your burst cadence will become vicious with the charge speeding up.

 

 - Deadshot Daiquiri – crit focus. XR3 thrives on crit multiplyers so this is a great way to get immediate results.

 

 Speed Cola: this is essential to QoL when you have the PaP mag problem.

 

 - Protective gear: get it early so you don't have to be punished when the window for charging is open. You will also stand closer in your line of sight.

 

 Upgrade Paths: Rarity Levels, PaP Levels and Elemental

 Early game rarity (Loadout Rarity:

 

 You'll notice the weapon's limitations, including its limited ammo and slow charging. If you find yourself starved, don't linger; push PaP quickly.

 

 - Pack-a-Punch:

 

 PaP 1: Expect close-range critical to increase from 2,160 to 2,376 when perks are added before rarity.

 

 - PaP 2: damage per projectile at base is 4,752. Multiplying this by 3 shots for each charge gives a high throughput.

 

 - Elemental Choice:

 

 Napalm Burst - Currently the best XR3 Elemental for scaling boss damage and DPS. Napalm can turn your Zersa gun into an effective melt tool.

 

 Max Rarity

 

 You can expect to get 38,000 Crit per projectile in the top tier. If you add napalm (57,000 per shot), your practical DPS spikes will be even higher.

 

 - If ADS delays persist after maximuming, you may need to adjust grips/lasers for quicker snaps.

 

 Salvage Economy - Monkey Bomb Loop Accelerates

 Chompy will eat a Monkey Bomb if it is made (1,000 salvage).

 

  - Max ammo refills grant you 2 monkeys back.

 

 - Sacrifice these two monkeys to save 2,000 per cycle.

 

 - You can easily snowball your way to 10,000 in a few rounds if you repeat the process per round.

 

 If you feel that the station has under-served you (e.g. only 500 ammo instead of 1,000 when in beta), you can assume it is a quirk. You can cycle again, or use a fresh maximum amount to reset.

 

 Real-World tests on Zersa and Melts HVT

 - Field Note: XR3 triple-shots and Double Tap shred Zersa faceplates at base rarity; cadence is key--count charges (1,2,3,4,5) and reposition yourself to the crit area.

 

 - Napalm or PaP?

 

 The crit ticks are in the 21k range very early. Maximum elemental pops can be 57k per pulsation. Bosses will disintegrate after a few volleys.

 

 - What it means: When you're dealing with bosses in rounds that are heavy (30+), accuracy and ammo discipline will be your biggest limiting factor, not raw damage. If you can maintain your crit discipline, and have the element on at all times, XR3 is a great tool for boss battles.

 

 How to Play: Micro-Flows and Collateral Lines

 If you want to line up trains then use the triple projectile to collateralize 4-7 zombies in Instakill. This is both efficient and quick.

 

 Avoid free-firing at long distances if you see damage dropping at mid-range.

 

 The XR3 punishes reloads that are too greedy because they encourage standing still.

 Why not use the second sniper? It's more convenient.

 

 You are right, the other sniper is more responsive at base thanks to its hipfire and snap feeling. XR3 destroys it more decisively with the full build. If boss time to kill and DPS late in the round are your priorities, XR3 will win; if snappier handling is more important, you'll prefer the other sniper.

 

 

 

 Q: Does Napalm have to be used?

 

 A: For maximum DPS and boss melts? Yes. You can experiment with different elements if you are overkilling and running out. However, current testing shows that napalm is the most effective element for XR3.

 

 

 

 Q: What is the fix for the PaP magazine bug?

 

 A: No, you can't. Plan accordingly. Carry Speed Cola. Manage reload windows and use salvage loops. Treyarch is expected to normalize magazine sizes at launch.

 

 

 

 Q: Can Double Tap be used with rapid charge ammo?

 

 A: Yes. Double Tap raises effective fire rate; rapid charge reduces charge delay. Together, the volley cadence tightens. This is how XR3 reaches a high DPS.

 

 

 

 Q: What attachments do I need to swap out if my mid-range feels off?

 

 A: A hybrid-barrel will provide you with both velocity and range. Also, make sure that your laser/grip combination still maintains ADS. If ADS seems slow, consider IMW instinct and a lighter stock.

 

 The following is a summary of the information that you will find on this page.

 You can build your XR3 Ion Sniper to be the most powerful Zombies loadout by focusing on crits, Napalm, and fast charge. The math is unapologetically silly--three-projectile charges, ~38k crits per shot, and elemental pulses that push toward ~294k DPS. If the base feels clunky to you, treat it as a boss-tool: upgrade into Double Tap (or Deadshot), Speed Cola, PaP early, fix your range/velocity, and run the "monkey-salvage" loop. If you do that, Zersas will fall in seconds and your collateral lines will become highlight reels.
