Lethal Company Inventory Mod is a type of mod that expands or reorganizes the item slots you can use in Lethal Company. Lethal Company players still look for better inventory control in 2026 because the default 4-slot setup fills quickly when a run demands tools, scrap, and team utility at the same time.
The important detail is that not all inventory mods solve the same problem. Some increase your main hotbar and give you more inventory slots for any item. Some add reserved slots for utility gear like a flashlight or walkie-talkie, which does not truly create a bigger main inventory but can feel like a major quality of life upgrade during normal gameplay. Some also bundle extra features such as faster swap behavior, UI cleanup, and hotkey improvements while remaining relatively unintrusive to the core game loop.
The most common reader question is simple: do you want just more room, or do you want the best all-around fix for running out of hands? According to Thunderstore listings and author documentation, the strongest options for most players are HotbarPlus by FlipMods for a configurable hotbar, Xiaohai_MoreSlot by XiaohaiMod for a simpler slot-count approach, and ReservedFlashlightSlot by FlipMods or ReservedWalkieSlot by FlipMods if utility gear keeps stealing your main hotbar space. This guide compares those options directly, explains where ReservedItemSlotCore fits in, and helps you choose the right mod setup without mixing in unrelated company mods or outdated picks.
What is Lethal Company Inventory Mod?
A lethal company inventory mod changes how your character carries and accesses items in Lethal Company. A lethal company inventory mod usually falls into one of two buckets: a mod that adds more main slots, or a mod that creates reserved utility slots outside the normal four-slot bar.
According to the author documentation for the mods covered here, the base point of comparison is the game’s default 4-slot inventory. That fact matters because every strong option below answers a different pain point:
- More inventory slots for general carrying
- A bigger or more flexible hotbar mod
- Dedicated utility space for flashlight or walkie use
- Faster swap behavior and cleaner UI
- Better quality of life without changing the game too much
In practice, the best pick depends on what keeps ending your runs. A solo player who always drops loot for a flashlight has a different need than a host who wants larger, synced inventory slots across a group. According to Thunderstore listings, some mods are also more feature-rich than others, so “best” does not always mean “most minimal.”
Top Lethal Company Inventory Mod Options Compared
According to the Thunderstore listing details and author documentation, these are the most relevant options for players who want lethal company extra item slots, a lethal company bigger inventory mod, or reserved utility space.
| Mod | What it changes | Best for | Important compatibility note | Main trade-off |
|---|---|---|---|---|
| HotbarPlus by FlipMods | Makes hotbar size fully configurable, adds hotbar/UI/QoL tweaks | Best overall hotbar mod and best all-around inventory fix | Hotbar size setting is host-only and syncs from the host | Not a minimalist slot-only mod; adds extra QoL features |
| Xiaohai_MoreSlot by XiaohaiMod | Lets you customize item slot quantity through config | Best for players who want a more inventory slots mod with a simpler focus | Author docs explain manual config editing; host-sync behavior is not detailed in the provided listing text | Fewer documented extras than HotbarPlus |
| ReservedFlashlightSlot by FlipMods | Adds a dedicated flashlight slot on the right side of the screen | Best if flashlight use keeps consuming a main slot | Author docs say to refer to ReservedItemSlotCore for latest compatibility | Does not increase main hotbar count |
| ReservedWalkieSlot by FlipMods | Adds a dedicated walkie-talkie slot on the right side of the screen | Best for crews that always carry comms | Author docs say to refer to ReservedItemSlotCore for latest compatibility | Does not increase main hotbar count |
| MijuSixSlots by GOJU_4678 (DEPRECATED) | Expands inventory from 4 slots to 6 | Only relevant if you are checking older pages or old installs | Author notes say all players should use it in multiplayer for best compatibility | DEPRECATED; readers should look at ReservedFlashlightSlot instead, plus active slot-expansion options like HotbarPlus or Xiaohai_MoreSlot depending the goal |
The quick takeaway is easy. If you want the most flexible answer, choose HotbarPlus. If you want a cleaner answer that simply changes slot quantity, Xiaohai_MoreSlot is the closest fit. If your problem is utility clutter rather than raw capacity, ReservedFlashlightSlot and ReservedWalkieSlot are often more essential than a bigger hotbar.
Detailed Breakdown of Each Option
According to the author documentation, each option below targets a distinct inventory problem rather than serving as a perfect replacement for the others.
HotbarPlus by FlipMods
HotbarPlus is the strongest all-purpose pick because it does more than just increase inventory slots. The author states that the number of hotbar slots is fully customizable in config, including more than the default 4, and that the setting is host-only and syncs from the host.
The Thunderstore listing also says HotbarPlus includes energy bars and lightning warning icons. The author documentation further says HotbarPlus fixes inventory UI positioning, can invert hotbar scrolling, removes the delay between swapping hotbar slots, and removes other forced delays between discarding, interacting, and activating items.
- Pros
- Fully customizable hotbar size
- Host-controlled slot setting that syncs with the host
- Strong quality of life package
- Faster swap behavior
- Better HUD readability
- Cons
- Not a pure “slot count only” mod
- Some players who want just extra room may find the extra features unnecessary
- Best for
- Players searching for a lethal company hotbar mod
- Hosts who want a shared, cleaner inventory experience
- Anyone who wants more slots plus faster-feeling gameplay
Xiaohai_MoreSlot by XiaohaiMod
Xiaohai_MoreSlot is the closest match for people asking Reddit-style questions like “is there a mod that just increases inventory slots and nothing else?” According to the author documentation, you can customize the number of item slots by editing the config file after installation.
The provided documentation is much lighter than the HotbarPlus page, and that simplicity may be exactly the point. According to the author, installation starts with BepInEx-BepInExPack-5.4.X, and the .dll file is placed in the Lethal Company\BepInEx\plugins folder.
- Pros
- Clear focus on custom item slot quantity
- Good fit for players who want a lethal company more inventory slots mod
- Fewer documented extras, which may feel more unintrusive
- Cons
- The provided listing text does not document the same QoL depth as HotbarPlus
- The provided listing text does not spell out host-sync behavior
- Best for
- Players who want extra slots without a larger bundle of changes
- Users comfortable editing a config file
ReservedFlashlightSlot by FlipMods
ReservedFlashlightSlot does not make the main hotbar bigger. ReservedFlashlightSlot instead gives you a dedicated flashlight slot on the right side of the screen, and the author says the slot can optionally be purchased at the terminal unless disabled in ReservedItemSlotCore config.
According to the author documentation, you can activate the flashlight anytime by pressing F, even with another item in your hands. The docs also say reserved slots stack vertically with other reserved slot mods, cannot be switched to by normal scrolling, and instead use Alt plus scroll for swapping between reserved items.
- Pros
- Frees a main slot for scrap or tools
- Flashlight access at any time
- Strong “global flashlight” style convenience during runs
- Integrates with the reserved-slot system
- Cons
- Does not actually add more main inventory slots
- Uses a separate reserved-slot interaction method
- Best for
- Players whose flashlight constantly crowds the main hotbar
- Crews that want utility access without constant hand management
If your problem is “I always lose one slot to a flashlight,” ReservedFlashlightSlot can feel better than a raw slot increase. According to the listing, that improvement comes from offloading utility rather than increasing your core carrying limit.
ReservedWalkieSlot by FlipMods
ReservedWalkieSlot follows the same reserved-slot logic, but for the walkie-talkie. According to the author documentation, the walkie slot can also optionally be purchased at the terminal unless disabled in ReservedItemSlotCore config.
The author also says you can activate and speak into the walkie anytime by holding X, even with another item in your hands. Like the flashlight version, ReservedWalkieSlot stacks on the right side of the screen and uses Alt plus scroll to access reserved items for actions like dropping, charging, or storing.
- Pros
- Frees a main slot for loot or tools
- Keeps communication available at all times
- Fits naturally with other reserved-slot mods
- Cons
- Does not increase the main hotbar
- Best value depends on how often your group uses walkies
- Best for
- Teams that treat communication as an essential part of the run
- Players who hate sacrificing a core slot to the walkie-talkie
MijuSixSlots by GOJU_4678 (DEPRECATED)
MijuSixSlots is clearly documented as increasing inventory from 4 slots to 6. According to the author documentation, it works through BepInExPack and can be installed through Thunderstore Mod Manager with dependencies.
The problem is simple: MijuSixSlots is DEPRECATED. As of 2026-08-26, readers should not treat MijuSixSlots as a front-line recommendation, and the active alternative named alongside it is ReservedFlashlightSlot if your real pain point is utility-slot pressure rather than raw capacity.
- Pros
- Clear 4-to-6 change
- Straightforward purpose
- Cons
- DEPRECATED
- Not the safest recommendation for a fresh install
- Best for
- Checking old references only, not building a new mod setup
How to Choose the Right Lethal Company Inventory Mod
According to the author documentation and the search intent behind general discussions, most players are not really choosing between “good” and “bad” mods. Most players are choosing between “more room” and “better organization.”
Use this decision framework:
- Choose HotbarPlus if you want the best overall package.
HotbarPlus is the right choice when you want more slots, better swap speed, UI cleanup, and extra quality of life touches in one mod.
- Choose Xiaohai_MoreSlot if you want a simpler slot-count change.
Xiaohai_MoreSlot is the better fit when your main requirement is a lethal company extra item slots mod without a broader feature bundle.
- Choose ReservedFlashlightSlot if flashlight pressure is the real problem.
A reserved flashlight slot often feels like a bigger inventory because a utility item stops occupying the normal bar.
- Choose ReservedWalkieSlot if your team always carries comms.
A reserved walkie slot is especially useful for groups where communication is constant and dropping a main slot feels costly.
- Treat “lethal company backpack mod” as a search intent, not a documented pick here.
According to Steam general discussions in the search results, some players want a store-bought backpack concept. No backpack mod is named in the approved options covered here, so the closest documented answers are a bigger hotbar or reserved utility slots.
Watch for these red flags:
- Deprecated pages.
Do not build a fresh loadout around MijuSixSlots (DEPRECATED).
- Confusing reserved slots with main slots.
ReservedFlashlightSlot and ReservedWalkieSlot improve carrying freedom, but they do not increase the normal hotbar count.
- Ignoring host behavior.
According to the author docs, HotbarPlus uses a host-only hotbar size setting, so multiplayer expectations should match the host’s setup.
If you are installing for the first time, use r2modman, Thunderstore, or Gale for the easiest setup flow. According to the author documentation, Xiaohai_MoreSlot can also be installed manually by placing the .dll file in the BepInEx\plugins folder and editing its config file afterward.
