The next Rust server update is scheduled to release on March 5th, bringing another round of improvements to ocean gameplay, AI behavior, and quality-of-life features. If you run Rust server hosting for a community, this is a solid patch to keep an eye on, especially with changes that affect player boats, Deep Sea events, and scientist combat.

Many of these features can already be tested through the Rust Staging Branch on Steam, which is useful if you want to validate changes early on a staging Rust server before pushing anything live.

How To Test The Update Early

The Staging client update is now available through Steam. To join, you must launch “Rust - Staging Branch” (not the standard “Rust” client).

From here, you have two options:

  • Quick testing: Join a random Staging server to get a feel for the update and check the new mechanics in action. This is the fastest way to preview changes, but you’ll be limited by that server’s rules, settings, and what you’re allowed to build or access.
  • Full testing and experimentation: If you want complete control to properly test features (like player boat building, Deep Sea timing, or scientist balance), the best approach is to set up your own staging Rust server. That gives you admin access, lets you spawn items, change conditions, and replicate your real server setup to see how the update behaves before it goes live.

Notable Changes In the March 5th Rust Update

Daytime and Lighting Tweaks

This patch includes several world and visual changes:

  • Daytime extended by roughly 20 minutes
  • Environmental lighting changes
  • Lowest “Max shadow lights” setting is now 1 (previously 0)

Improved Spawn Fallbacks

If beach spawns are blocked, the game will now offer alternate spawn locations at:

  • Fishing Villages
  • Harbors

This should reduce cases where players repeatedly spawn into awkward or unusable spawn zones, like someone's compound.

Modular Boats: More Building And Better Combat Mechanics

Player boats receive a large set of upgrades in this Rust update, focusing on building usability, combat interactions, and overall feel.

New Deployables Supported On Boats

You can now use the following:

  • Electricity (Lights, Solar panels, Batteries)
  • Industrial
  • Watering
  • Wallpaper
  • Planters
  • Traps (Shotgun traps, Flame turrets, Tesla coils)

What you cannot place on boats:

  • Turrets
  • Sam Sites
  • Windmills

This brings boats closer to a “floating base” functionality, now fully supporting farming and industrial setups for storage automation.

Boat Behaviour, Building Mechanics, And Cannon Changes

Additional updates include:

  • Added ADS aim sway while traveling on moving player boats
  • Time limit removed for destroying boat-building pieces while in edit mode
  • Player boats are slowed when hit by cannonballs
  • Added deployable snapping on player boats
  • Further improvements to boat-shaped drag
  • Players receive damage protection when mounted to cannons
  • When sunk, boat pieces can be individually destroyed

Deep Sea: More Structure, Better Timing, Less Predictability

Deep Sea continues to get tuned, and these adjustments should make it feel less predictable while improving long-term value.

Loot And Access Changes

  • Some Deep Sea loot will respawn
  • RHIBs have been removed from entering Deep Sea and only modular boats can access the border now.
  • Added static boat building stations to Deep Sea islands

Until now, the deep sea was first-come, first-served. If someone already got all the loot, the deep sea would be pretty much empty.

Loot respawns will drastically change the life cycle of the deep sea and bring more initiative to venture out, even if you are late to the party when it first spawns. Just make sure to have your boats already built, as RHIBs are now forbidden.

Event Timing And Open Mechanics

  • Deep Sea opens on a random side of the map
  • It will never repeat the same side twice in a row
  • Deep Sea is not automatically open on map wipe
  • Downtime is now 1.5 to 2.5 hours
  • Deep Sea now plays a global sound when opening

AI Updates: Scientists Behave Better

The update improves newer scientists' behavior while keeping older scientists' AI unchanged.

  • Fixed newer scientists shooting through smoke
  • Newer scientists now use flashlights
  • Newer scientists now use lasers

These are small changes on paper, but they were much needed. No one enjoys being cheated on by scientists able to see through smoke, and the added attachments can meaningfully affect night encounters. However, these changes are only applying for NPCs found on Oilrigs and the Deep Sea. Every other NPC is still using the old mechanics, but hopefully those get some updates soon, too.

Scientist Damage vs Armor Has Changed

Another very impactful change for NPCs is the armor and damage balancing tweaks, and how the new scientists calculate damage against player armor.

Old protection formula

Sum of all clothing protection / 6

New protection formula

(sum of head × 1 + sum of body × 1.5 + sum of legs × 0.5) / 3

What this means: armor is effectively stronger against these newer scientists. Heavy plate, for example, behaves closer to how it does in player vs player damage expectations. Old scientist AI is unchanged.

If your Rust server relies heavily on PvE (or runs events with lots of scientists), this change could alter your difficulty tuning. There's no known convar to alter this so far, but maybe it gets added in the future.

Misc Fixes And Additions

  • BBQ is now skinnable
  • Painting QoL changes
  • debug.showentities command added to show invisible entities
  • server.randomize_seed convar added, allowing random seed rotation on server launch. (Every server restart, the seed will change)
  • New container fill commands: fillcontainer and fillcontainer_radius for randomized inventory testing
  • Various bug fixes
Tip: If you plan on using server.randomize_seed be aware that on every server restart, the seed will change as long as this convar is in your server config.

Preparing For Wipe Day And Testing On A Staging Rust Server

If you manage Rust server hosting, the best move is to test major gameplay changes before wipe day, especially when PvE combat and respawn systems are being adjusted. Running a staging Rust server lets you verify plugin compatibility and balance changes without risking your main community server.

This is especially useful in this update for checking:

  • Deep Sea opening/downtime behavior and loot respawns
  • Any lighting changes that impact visibility or performance
  • PvE balance changes due to the new scientist armor formula

If you’re using a dedicated Rust server host, like Pine Hosting, you can quickly spin up a test environment to trial the Rust server update, then roll into wipe day with confidence once everything looks good.
