Rust's June 4, 2026 force wipe is one of the biggest content drops in the game's 10-year history. Facepunch shipped a full player model overhaul, three brand-new loot-only items (the M16A2 burst rifle, Ballistic Armour, and BDU clothing), an experimental opt-in navmesh, and a noisy PSA for anyone running a 1000Hz mouse on the Unity 6 client. Here's what changed, and what server owners need to know before tonight's wipe-night rush.
Release Date and Wipe Schedule
The "Built Different" update went live on Thursday, June 4, 2026 at roughly 20:00 UTC, the same window as every Rust monthly. If your server runs on the official "wipe on every monthly" schedule, your map, world, and player data have already cycled. Blueprints are wiped on this update too, since it's a force wipe month.
The First Player Model Overhaul in 10 Years
The headline feature is a ground-up rebuild of the player model. The old model had been in the game for almost a decade, and Facepunch finally tore it out rather than continuing the long string of band-aid fixes. The new model brings:
- More realistic proportions on a new rig, with new anisotropic shaders that make hair feel more natural
- An expanded head and hair seed pool, each head with unique materials and improved eye lighting
- Every clothing asset updated to fit the new rig (older skins look noticeably cleaner)
- A modernised art pipeline that makes future character updates much faster to ship
Your face will change after the wipe, but race and gender seeds were intentionally preserved, so the random seed you've grown attached to over the years stays consistent. Facepunch has confirmed internal performance metrics are positive and will be monitored closely after release.
New Loot-Only Gear: M16A2, Ballistic Armour, BDU
For the first time in a long time, Rust is getting fresh end-game gear. All three new items are loot-only and cannot be crafted:
- M16A2 burst rifle: military-grade three-round burst with excellent accuracy and a high rate of fire at medium range. Lower per-shot damage than the LR-300 to balance the burst potential.
- Ballistic Armour: a new top-tier armour set roughly comparable to metal armour with plates, found through end-game loot.
- Battle Dress Uniform (BDU): loot-only clothing with a slight protection upgrade and a few trade-offs elsewhere.
Pushing the strongest gear into loot tables rather than the workbench is a real shift in progression. Expect aggressive roof camping at high-tier monuments and a sharp spike in chopper crashes in the first 48 hours of the wipe.
Animation System Rebuild and 3/4 Weaver Stance
Facepunch also rebuilt the animation foundation. The single monolithic animator state machine that handled over 250 animations is being split into smaller subsystems, starting with a torch-specific rig that finally lets your left arm move while you hold the torch. Weapon aiming has moved from a forward-facing stance to a 3/4 weaver stance, which reduces clipping on stocks and just looks better at distance.
The team explicitly chose to keep input response snappy rather than chase silky transitions, after watching other shooters get burned by overly smooth animation blending. Combat should feel exactly as responsive as last month.
NEW Opt-In Navmesh (Read This If You Host)
This is the change most likely to affect your server. Facepunch shipped a first pass on replacing Unity's navmesh with their own, available behind a startup flag:
-useNewNavmesh
Add it to your server startup arguments to opt in. You can visualise it in-game with rustNav.draw. The new navmesh enables:
- Animals and scientists entering simple player bases with no doors, groundwork for keeping sheep, cows, and dogs
- Fewer random NPC deaths from Unity failing to path on convex or concave terrain
- A foundation for updated scientist AI on the Cargo Ship and Excavator
- Better and cheaper flanking for new scientists via custom A* costs
It's off by default. Test it on a staging server before flipping it on production, since this is the first month it's shipped.
Industrial Decor Pack and Bowless Crossbow
The monthly cosmetic drop is the Industrial Decor Pack: 20 deployables and skins (Industrial Shelving, Storage Barrels in horizontal and vertical varieties, an Auto Turret skin, Large and Electric Furnace skins, a Garage Door skin, painted concrete floor wallpapers, sprays, and emojis). Worth flagging if your server enforces deployable caps, since stacked shelving and barrels can balloon entity count fast.
The new Bowless Crossbow skin also drops this month, with a unique pulley animation built around salvaged workshop components.
PSA: 1000Hz Mice Are Causing CPU Frame Drops
Facepunch flagged this directly in the patch notes: the Unity 6 upgrade changed how mouse inputs are processed, and 1000Hz+ polling rate mice are now causing significant CPU overhead and frame drops. The temporary workaround is to drop polling to under 1000Hz in your mouse vendor software (Logitech G HUB, SteelSeries GG, Razer Synapse, etc.). A proper engine-side fix is in progress.
If you're seeing tickrate drops in console at the same time as your players complain about FPS, this is probably the cause. Test with one player on a low polling rate before assuming it's a server-side issue.
Server-Side Performance: Pool Rewrite and StringView
Two under-the-hood server changes worth knowing about:
- The internal object Pool has been rewritten to a lock-free design, cutting mutex contention in multithreaded entity-snapshot work. A fallback exists if it misbehaves: run
pool.usemutexpool 1in console to revert to the old implementation. - StringView is replacing string allocations in the console command pipeline, which saves 60+ allocations and 4KB+ of memory per 6-argument command call. If you run custom server plugins that do clever string parsing on console args, expect a brief compatibility check. A
GetStringcompatibility shim is provided.
What This Means for Your Server
Practical checklist for the first 72 hours after wipe:
- Schedule a backup before flipping
-useNewNavmeshon, if you're testing the new navmesh - Update Oxide/uMod or Carbon before restarting your server. The Pool and StringView changes are intrusive, and modding frameworks typically ship a patched build within hours of a force wipe
- Communicate the 1000Hz mouse PSA in your Discord. Half the "your server is laggy" complaints in the next week will be client-side
- Expect a player spike: monthly wipes always draw returning players, and the new player model plus the first new top-tier weapon in years amplifies that. Watch your slot count and RAM headroom for the first 48 hours
- Hit validation for parented players (boats, hot air balloons) has been improved, so fewer "projectile invalid" rejections. No action needed, but worth knowing when players ask
Verdict: Worth Coming Back For
This is one of the most substantial Rust monthlies in years. The player model overhaul alone justifies coming back, and the M16A2 plus Ballistic Armour finally give end-game loot something fresh to chase. The opt-in navmesh is the deeper play: once Facepunch flips it on by default in a couple of months, animal AI and scientist AI both get a real foundation for upgrades. If you've been considering rebooting your community, this is the wipe to do it on.
Host Your Rust Server with DoomHosting
Running a Rust server on a fresh wipe night means uptime matters. DoomHosting's Rust hosting ships on Ryzen 9 hardware, gives you full Oxide/uMod support with one-click installs, and the FTP access you need to drop in -useNewNavmesh and other startup flags in under a minute. Plans scale from solo wipe servers up to 100-slot communities, with DDoS protection on every tier.
Built Different is the kind of update that brings people back to Rust. Make sure your server is the one they log into.
