Solo Pile Up Glitch BO7 Zombies — Infinite XP Trick Explained
This guide walks you through the entire process to consistently trigger and run the new pile up glitch in BO7 Zombies solo, turning normal runs into a reliable XP loop session. I'll cover the setup, exact steps, recommended weapons and equipment, map positioning, risk management, troubleshooting, and how to scale the method safely to maximize your gains. Every section is written to be followed in-game without guesswork — from opening moves to maintaining the pile and exiting cleanly.
What this accomplishes
Create a dense, stationary cluster of zombies that can be repeatedly kited or deleted for rapid XP and resource gains.
Maintain the pile solo without needing host exploits or teammates.
Keep consistent safety windows so runs are repeatable and low-risk.
Convert regular matches into sustained XP farm sessions for weapon levels, account levels, or challenges.
Before you begin: terminology and quick tips
"Pile" — the stacked group of zombies bunched up in one location.
"Kite loop" — the player movement path used to keep zombies clumped and coming back.
"Reset window" — an in-game moment when zombies stop spawning or pathing properly; this is when the pile stabilizes.
Quick tip: patience beats haste. Set up carefully and the run will pay dividends in long XP sessions.
Required game state and basic conditions
Play solo on a standard BO7 Zombies match. Some settings or playlist variants may affect spawns; this method assumes default solo match rules.
Aim for low to mid-rounds to set the pile; once established, you can extend to higher rounds safely.
Loadout: bring weapons and gear optimized for crowd control and ammo conservation (more details in the Loadout section).
Preparation: inventory, perks, and loadout
Perks and utilities to bring
Quick Revive (where applicable) is useful even in solo to reduce downtime from mistakes.
A movement or stamina-boosting perk or field upgrade to help maintain kiting consistency.
Any perk that increases ammo economy or reload speed improves sustainability.
Recommended weapons
Primary crowd-control weapon: a high-rate-of-fire automatic or light machine gun with good ammo pool and predictable recoil.
Secondary: a high damage, precise weapon for emergency one-shot kills (e.g., marksman rifle or shotgun depending on map).
Lethals and tacticals: at least one stun or flashbang-equivalent to temporarily freeze movement if available; frag or throwing explosives are optional but can help thin down high-health targets.
Consumables and tactical items
Ammo boxes or field upgrades that replenish ammo will extend sessions.
Grenades with blast radius are useful to condense straggling zombies into the pile during set-up.
Key player skills and movement practice
Practice the chosen kite path in safe rounds to learn recoil patterns and safe timing windows.
Work on immediate reaction strafing and hit-and-run timing to avoid getting boxed in.
Map selection and ideal pile locations
How to choose the best spot
Look for choke points where corridors, doors, or map geometry funnel zombies into a narrow approach.
Locations near a reliable spawn cluster and with limited entry vectors are ideal.
Avoid open areas with multiple approach angles; you want predictable pathing.
Examples of ideal geometry
Long corridors ending in a small room.
Stairwells where zombies fall into a landing area and must funnel through a single doorway.
Areas with a corner or object that causes AI pathing to momentarily confuse and gather, useful for forcing stack behavior.
Setup phase: creating the pile
Early-round actions (Rounds 1–3)
Clear a small area and identify your choke point.
Lure a few zombies through the opening and test whether they follow reliably.
Use one or two controlled kills to leave small numbers alive that will continue to path toward you.
Mid-round actions (Rounds 4–7)
Start consolidating zombies in the selected choke by intentionally slowing kills and letting pathing do the work.
Use grenades or crowd-control to nudge stragglers into the main group.
Begin your first full kite loop to test how the group behaves over multiple rotations.
Creating the first stable pile
The pile forms when zombies repeatedly path into the same collision area without dispersing.
Trigger the reset window by moving slightly away and returning; if zombies regroup faster than they disperse, you have a viable pile.
Watch for consistent pathing: if many zombies take alternate routes, try a different choke.
Precise movement: the solo kite loop
The loop outline
Use a simple oval or figure-eight path that keeps the pile compressed while providing space to shoot.
Maintain a constant pace — sudden stops or jagged movement causes AI pathing to break and scatter the pile.
Timing, spacing, and rhythm
Stay just out of melee range to keep zombies targeting you while allowing room to circle.
Fire in short bursts to conserve ammo and to avoid long recoil recovery that interrupts movement.
Reposition after every 3–5 magazine bursts to avoid being flanked by stragglers.
Visual cues that the loop is working
The pile stays within a compact area and returns to it each loop.
New zombies entering the area follow the same path and join the stack rather than peeling off.
The group's bounding box stays smaller than one room's width.
Stack maintenance: keeping the pile tight
Using map features
Use corners, steps, or small geometry to anchor the pile; zombies will bunch up against surfaces.
If zombies begin to rift apart, briefly use a flash or stun to reset their pathing and then resume the loop.
Weapon usage for control
Use low-knockback weapons when you want zombies to stay tightly packed.
Use low-damage, high-rate-of-fire bursts for steady thinning; reserve heavy hits for when the pile overflows or the pile becomes too large.
When to intentionally thin
If the pile reaches a size where pathing starts to break or zombies start clipping through the environment, thin the outer rings with grenades or a sustained spray.
Aim to maintain a stable equilibrium where kills slightly outpace spawns without collapsing the pile.
Triggering the unlimited XP behavior
What to watch for
The glitch usually activates when the pile reaches a higher-than-normal entity density in a confined collision zone while the player's movement and camera angle cause the game to repeatedly award kill XP for clustered entity deaths that register as new hits due to server-side bookkeeping.
Signs the glitch is primed: repeated XP ticks that appear larger than a single kill once the pile is being damaged.
Activation sequence
Build and stabilize the pile per previous sections.
Use controlled damage windows — short sustained bursts that cross-check hit registration.
If the game starts showing repeated XP numbers in quick succession even while zombies appear to be dying slowly, continue the loop; the system is looping XP credit.
What to avoid while triggering
Avoid teleporting to other areas of the map or opening/closing doors that drastically alter spawn behavior.
Don’t use abilities or field upgrades that drastically change entity physics (these can break the pile or reset the server-side counters).
Damage economy and ammo conservation
How to stretch ammo for long runs
Use alternating fire patterns: one high-power burst followed by low-power suppression.
Rely on melee only for very low health stragglers; reserve ammunition for maintaining the pile and securing the trigger window.
Use resupply points or ammo drop field upgrades at planned intervals.
When to reload
Time reloads to the moment the pile is artificially thin (e.g., after a grenade clears the outer ring).
Use quick-reload perks or weapons with faster swap speeds to minimize downtime.
Risk management and safety nets
When things go wrong
If zombies break the pile and start flanking, immediately move to a nearby fallback choke and re-establish a smaller pile.
Use a tactical stun to buy time while resetting the loop.
Death prevention strategies
Keep an escape path always open — never funnel yourself into a corner without an exit.
If multiple zombies become unmanageable, reset by performing a controlled backtrack to a pre-cleared area and then rebuild.
Scaling and session planning
Time budgeting for XP runs
Plan sessions in blocks (30–60 minutes) to avoid fatigue and accidental mistakes that break the pile.
Track your XP per block of time early on so you can judge efficiency and make small adjustments.
When to push for higher rounds
After establishing consistent pile behavior at moderate rounds, slowly push the round cap while monitoring entity behavior.
Higher rounds increase risk: zombie health, damage, and pathing oddities can break the loop, so proceed incrementally.
Optimizations: small changes that add big gains
Loadout micro-optimizations
Use attachments and perks that increase magazine size and reduce reloads.
Attach recoil control and stability mods to ensure consistent aim while moving.
Camera and sensitivity tweaks
Set sensitivity to a level that allows quick, precise aim while maintaining smooth movement.
Small changes to camera pitch can sometimes affect how the pile paths — test in practice rounds.
Audio and UI cues
Turn up subtle sound cues that help you track off-screen zombies.
Use HUD elements conservatively; too much on-screen clutter can hide important visual cues for pile behavior.
Troubleshooting common failure modes
Pile disperses after forming
Cause: player movement pattern inconsistent or map spawn variance.
Fix: slow down the loop, tighten the turning radius, and re-anchor to a different piece of geometry.
XP ticks not appearing
Cause: trigger window not reached or server/client hit registration inconsistent.
Fix: reposition slightly and attempt a new activation sequence; if persistent, restart the match and reattempt from a clean setup.
Zombies teleport or clip through geometry
Cause: high entity count or map-specific collision bug.
Fix: thin the pile immediately and avoid areas known for clipping; move to a different choke.
Ethics, account safety, and practical considerations
Responsible use
Tools and glitches in live games can be fragile. Use discretion: prioritize enjoying the game, and be mindful of game policies.
Frequent exploitation in public or competitive ladders risks detection or action in some systems; consider private or practice sessions if you prefer risk-averse play.
When to stop
If the pile causes severe desync, rubber-banding, or persistent server instability, end the session and restart to avoid device or account issues.
Advanced variants and experiments
Multi-pile chaining
Some players create two adjacent piles and alternate between them to further trick spawn behavior; this requires more movement precision and a reliable escape plan.
Intentional spawn manipulation
Using doors or teleport points can sometimes shift spawn loci; experiment in private matches to see which spawns are most predictable for long sessions.
Weapon-specific tactics
Some weapons with explosive area damage can maintain pile integrity better than high-knockback platforms; test both to find the most stable for your play style.
Recording, monitoring, and refining your runs
How to track improvements
Record key runs and review where the pile breaks or XP ticks fail; small movement or aim adjustments often fix repeated failures.
Keep a short log of run duration, average XP per minute, and incident notes (e.g., "clip at stairwell round 12").
Sharing findings
When you refine a reliable setup, document exact positions, loop path, and gear choices so you can reproduce or adapt the method across similar maps.
FAQ
What round is best to set the pile up?
The best rounds are typically mid-game (rounds 4–7) because there's a steady flow of zombies without extreme health values that make early consolidation difficult. Once the pile is stable you can extend to higher rounds.
Does this work on any map in BO7 Zombies?
It works best on maps with tight choke points and predictable spawn geometry. Some maps with open layouts or multiple entry angles will be harder to manage; always test different chokes before committing.
Will this get me banned or penalized?
Game policies vary. This guide describes in-game behavior and movement techniques; persistent exploitation in public competitive settings may attract attention in some communities. Consider using private games or practice sessions if worried about policy enforcement.
Can I do this with a low-level weapon or loadout?
Yes. The method relies more on movement and pathing than raw weapon power. Use weapons that offer good sustain and control; accuracy and ammo economy are more important than one-hit power.
How long can an XP loop session last?
Sessions can last as long as you can maintain the pile, your ammo, and your concentration. With planned resupplies and steady play, multi-hour sessions are feasible; build breaks into your schedule to avoid mistakes.
What happens if the pile breaks at a high round?
If the pile breaks, your best option is to move to a prepared fallback choke and re-establish a smaller pile. If overwhelmed, use evasion and reset rather than trying to solo-clear everything.
Are certain tactics banned from online leaderboards or tournaments?
Tournament and leaderboard rules differ. For official competitive contexts, check the event rules; avoid techniques flagged as exploits in their policy language.
Final checklist before you start
Choose and test your choke point in rounds 1–3.
Bring weapons and attachments that prioritize magazine size and stability.
Practice the kite loop once without attempting the trigger to learn timing.
Keep a fallback exit and a stun/flash for emergency control.
Record your first full run so you can refine movement and reload timing.
Closing notes
Follow the setup and the movement patterns here to consistently create a stable pile and exploit the XP loop effect in solo BO7 Zombies runs. The method rewards patience, consistency, and small optimizations: once you find a setup that behaves reliably, you can scale it up for long XP sessions and rapid progression.
