Base Sim: Planner for Rust

Base Sim is a base and raid planner for the game Rust. Design a base on your phone the way you build it in the game, see what it costs and what it eats in upkeep, find out where raiders get in cheapest, then walk through it in first person and check every room and doorway.

BUILD LIKE IN THE GAME

• Pieces snap together as they do in Rust: square and triangle foundations, walls, doorways, windows, wall frames, half and low walls, floors and floor frames, roofs, U, L and spiral stairs, ramps and steps.

• Doors, double doors, garage doors, hatches, window bars, embrasures, shop fronts, high external walls and gates.

• About 35 deployables with their own models: Tool Cupboard, boxes, lockers, furnaces, workbenches, turrets, traps, barricades and more.

• Sizes and placement rules are taken from the game files: two large boxes fit in an L in a 1x1, the cupboard does not stand on a floor grill, traps hang on walls and ceilings.

• Stability works: floors hold on walls, a few squares hang free, and whatever loses its support falls.

• Twig, wood, stone, sheet metal and armored, each with an outer and an inner side. A wall with its soft side out is flagged.

• Half storeys, mirror building, floor cut-away, top view, copy, move and rotate whole groups, undo and redo.

KNOW THE PRICE

• Build cost and daily upkeep update as you place pieces.

• Upkeep follows the game's brackets, per resource.

RAID IT BEFORE THEY DO

• Raid analysis finds the cheapest way from outside to the Tool Cupboard and shows which walls, doors or floors to break and how many rockets, C4, satchels or explosive rounds it takes.

• Raid simulator: pick an explosive, hit the base and watch the sulfur count. Splash damage works as in the game: a rocket into the joint of four walls hurts all four.

WALK THROUGH YOUR BASE

• Step inside in first person: a stick to walk, drag to look around, jump onto foundations, crouch under low floors, climb the stairs, open and close doors.

• Build, upgrade and demolish on foot: take the building plan or the hammer and aim with the crosshair, as in the game.

CALCULATORS

• Explosives for a list of targets, upkeep, recycler output, CCTV codes of monuments, time to the next forced wipe.

YOURS, OFFLINE

• Everything is stored on your device. No account, no ads, no tracking, no internet needed.

• Share a base with a friend as a short text code that fits in a chat message.

• Ready-made starter bases to open and rebuild.

• 21 languages.
