Utility Support Slot
This mod allows you to carry one utility (Solo Silo designator or C4 detonator) alongside another support weapon. Two utilities or two ordinary support weapons do not form a pair, so you cannot carry two EATs, for example.Installation and requirements
Requires HellForge on game build 25480438, with mod SDK 11 or newer. Import the release ZIP through HellForge's mod manager and enable Utility Support Slot, then restart. This mod only works for HellForge, not the current live game.Remove any older USS test build or Lua copy from the same setup before enabling this version. They should not run together.
The Mod Options Menu and Mod Bindings Menu, included in CowboyBingus's HellForge Vanilla Plus Megapack, are optional. Integration currently supports Megapack 0.2.1. Without both working menus, USS uses its own menu instead.
Controls
Default: press your support binding while your support weapon is already drawn to swap the pair. On controller, hold the weapon-switch button while support is drawn.Dedicated: use Utility Weapon to draw the utility directly. Pressing it again leaves the utility drawn, like vanilla. Other weapon controls behave as normal. A lone utility can also be drawn with the normal support control.
Without the optional menus, open Options > USS to choose Binding Mode and assign Utility Weapon. The standalone default is 6; the assignment accepts keyboard or controller input.
With the optional menus, choose Binding Mode under Options > MODS > Utility Support Slot and press APPLY. Assign Utility Weapon under Utility Support Slot on the keyboard/controller binding pages. That external binding starts unbound. Release the control after changing modes before using it again.
The external menus save their own choices. Your standalone choices are kept separately and are used again if the external menus are unavailable.
Pickup and recovery
Pickups follow the game's Switch Weapon On Pickup setting. With No, your previously selected weapon is restored; replacing an already drawn utility keeps the new utility drawn. Replacing either weapon keeps the other one and drops the old weapon like vanilla. Dropping or expending one weapon restores the remaining weapon. Dying drops both weapons like vanilla.Known limitations and multiplayer support
The game still has one support slot. The mod tracks the other weapon separately and keeps it attached to your character.Hosting and joining have been tested with two computers. More players are welcome to try it and report issues.
- A brief switch through your primary weapon can be visible during handling.
- Players joining mid-mission may not see your stored weapon until you swap weapons.
- Resupplying from another player's supply backpack does not refill the stored weapon.
- Leaving a mission with a pair may lose the stored weapon.
- Mods that change support weapon pickup or inventory slots can conflict with USS.
Credits
The gameplay logic is mine, but I had GPT-6.1 Sol help with research, implementation, debugging, and documentation.Big thanks to CowboyBingus for the Bingus Shared Loader, Mod Options Menu and Mod Bindings Menu. The original Lua version and the native menu work benefited from these projects. Reused menu code is covered by the included Zero-Clause BSD license.
I'd also like to thank SkyeShade, creator of HellForge and HD2Runtime, and notzelda, creator of LinksLinkToMemory, for their development and research tools. They helped me inspect live game state, understand weapon and multiplayer behavior, and run experiments throughout development.
