Rust Trio Base Design (2026)
For three-player teams · 3x3 core plus honeycomb ring, two storeys, sheet metal throughout
A group base with enough storage and defensive tiles for three players and their gear. Usually a 3x3 or compound with peek-downs over the entrance.
Trio Base build cost
The reference build we cost is a 3x3 core plus honeycomb ring, two storeys, sheet metal throughout — 62 building blocks plus doors and a tool cupboard. Every rate below is what the game charges for that piece: the twig it is placed as, then the upgrade. A floor or roof costs half a wall, a doorway or window 70%.
| Piece | Qty | Cost each |
|---|---|---|
| Sheet metal foundation | 12 | 50 wood + 200 metal frags |
| Sheet metal floor | 9 | 25 wood + 100 metal frags |
| Sheet metal wall | 26 | 50 wood + 200 metal frags |
| Sheet metal doorway | 5 | 35 wood + 140 metal frags |
| Sheet metal wall frame | 1 | 25 wood + 100 metal frags |
| Sheet metal roof | 9 | 25 wood + 100 metal frags |
| Sheet metal door | 4 | 150 metal frags |
| Garage door | 1 | 300 metal frags + 2 gears |
| Armored door | 1 | 20 HQM + 5 gears |
| Tool cupboard | 1 | 1,000 wood |
| Total | 11,100 metal frags · 20 HQM · 3,550 wood · 7 gears | |
Trio Base upkeep
Rust bills upkeep by building-block count: 10% of build cost per day for the first 15 blocks, 15% for the next 50, 20% for the next 125 and 33.3% after that. At 62 blocks this design pays a blended 13.8% a day, doors included; the tool cupboard itself costs nothing to keep.
Over a full seven-day wipe cycle that is 10,717 metal frags, 21 HQM — the number worth checking before you commit to a size. Work out how long your TC lasts.
What it costs to raid
Cost of the cheapest route from outside to the loot room, searched by the base planner on the exact piece list above — doors included, because a door on the outside is what a raider actually breaks.
| Raider has to break | Rockets | C4 |
|---|---|---|
| 1× Sheet Metal Door | 2 | 1 |
| Total | 2 | 1 |
That is 2,800 sulfur in rockets, or 2,200 sulfur in C4. The cheapest method that can break the whole path is 63× explosive 5.56 ammo at 1,575 sulfur. Compare every explosive.
