Mobile Fortress

Mobile Fortress adds a set of deployable large vehicles to RimWorld1.6, built on VehicleFramework. You can build a deployed fortress hull, place compatible turrets on its central deck, and then launch the entire platform into a mobile vehicle that can move, fight, transport pawns, and redeploy.

This mod is intended for colonies that enjoy large engineering projects, base defense, mobile firepower, vehicle warfare, mid- to- late- game resource investment, and heavy sci- fi machinery.

Current Status

This mod is still in public beta, but the main gameplay loop is playable. Current features include fortress construction, deployed/vehicle form conversion, deck turret capture and restoration, repairs, modification modules, shields, core modules, and the mobile arsenal.

Please treat this as a playable beta rather than a finished release. Turret compatibility, special weapon visuals, balance, and large- size testing will continue to improve.

Main Features

– Adds 6 mobile fortress sizes: MF- 03, MF- 05, MF- 07, MF- 09, MF- 11, and MF- 2015.
– Supports switching between deployed form and vehicle form.
– Deployed form provides a central deck area for compatible standard turrets.
– Deck turrets can be captured and converted into mobile mounted turrets.
– Captured turrets are restored when the fortress is redeployed.
– Vehicle- form turrets can search, aim, fire, and support forced target commands.
– Mobile fortresses use chemfuel for movement, turret fire, and some special systems.
– Made from metallic materials, with durability and protection affected by material.
– Can be repaired by colonists through construction work.
– Dedicated modification tab with armor, drive, cargo, control, core, and auxiliary modules.
– Shield generator module provides a large energy shield against incoming damage.
– Mobile arsenal module scans carried mechanoids as templates and fabricates temporary combat units.
– Mod settings allow tuning health, shield strength, turret fuel use, arsenal fuel use, and temporary unit service time.
– Supports English and ChineseSimplified.

Mobile Arsenal

The mobile arsenal is a core module. Once installed, the fortress can scan player- owned mechanoids currently loaded inside the vehicle and store them as production templates. You can then create production bills in the arsenal tab and spend the fortress’s own chemfuel to fabricate temporary combat mechanoids in the field.

These units automatically move, pursue, and attack enemies. They are not permanent colony mechanoids and cannot be kept as cheap long- term labor or permanent army units. After combat is over, they will eventually deactivate.

Larger fortresses run the mobile arsenal more efficiently. Smaller fortresses can still install it, but production is slower and more fuel- intensive.

How to Use

1.Enable Harmony and VehicleFramework.
2.Find the VehicleFramework- related build category.
3.Build a deployed mobile fortress.
4.Load it with chemfuel.
5.Build compatible turrets on the central deck.
6.Use the deck inspection command to check the deck.
7.Use the launch command to convert the fortress into a vehicle.
8.In vehicle form, move, fight, transport pawns, force turret targets, or redeploy.
9.Open the modification tab to install modules.
10.After installing the mobile arsenal, load player- owned mechanoids, scan templates, and set production bills.

Requirements and Compatibility

Required mods: Harmony, VehicleFramework.
Supported version: RimWorld1.6.
Languages: English, ChineseSimplified.

This mod can usually be added to an existing save for testing, but backing up your save is recommended. Removing it from a save after use is not recommended.

The mod works best with standard turrets and normal building workflows. Highly customized turrets, special projectiles, beam/laser weapons, custom turret drawing, complex multi- turret mechanoids, or mods that deeply rewrite vehicles or damage flow may have partial compatibility or visual limitations.

Known Limitations

– Some beam/laser effects may be briefly hidden by the fortress chassis near the muzzle.
– Some custom- drawn turrets may show incomplete visuals after conversion.
– Highly customized weapons and special turret mechanics may not be fully covered.
– MF- 2015 is extremely large and is best suited for testing or resource- rich mid- to- late- game colonies.
– The current version includes a narrow filter for confirmed harmless known load warnings related to certain vehicle- container cases. Unrelated save errors are not hidden.
