Extra Inventory Slot

Adds a purchasable upgrade to R.E.P.O. that gives you one extra inventory slot, up to a maximum of 6 slots per player.

The new slots are runtime clones of the vanilla slot, so they use the same sprite, frame, font, spacing, hover animation and battery/ammo widget. You should not be able to tell which slots are modded.

Features

• Purchasable upgrade. A pink upgrade pack appears in the shop and at the upgrade stand alongside the vanilla ones, priced at $25K–$30K — deliberately more expensive than vanilla upgrades. Buy it, take it to the truck, and use it like any other upgrade. It has its own front artwork, so it is not mistaken for a recoloured Grab Strength.

• Up to 3 purchases per player, for 6 slots total. Per-player, exactly like Health or Stamina.
• Number keys 4, 5 and 6 select the new slots, using the game's own input path — same tap to equip, tap again to unequip, same cooldown.
• The whole slot row stays centred. With 6 slots the HUD re-lays-out symmetrically rather than growing off to one side.

• Survives everything vanilla slots survive: level transitions, the truck, saving and loading, and rejoining.
• Ammo and battery bars work in the new slots, exactly as in slots 1–3.

⚠️ Emote keys 5 and 6

In vanilla, keyboard 5 and 6 are bound to Expression 1 and Expression 2 (emotes). This mod gives slot selection priority on those keys, so those two emotes will not fire on 5 and 6 while the mod is active.

You have two ways to get them back:

• Rebind the emotes in Settings → Controls. The mod matches on the actual binding, not the physical key, so once an emote lives on a different key it works again immediately.
• Or set SuppressConflictingBinds = false in the config, which lets both fire on the same press.

Emotes 3–6 (keys 7, 8, 9, 0) are untouched. Key 4 is unbound in vanilla, so nothing is lost there.

Multiplayer

• Every player needs the mod. Slot counts are per-player and host-authoritative.
• The host especially needs it. If the host does not have the mod the upgrade never spawns, so everyone simply stays at 3 slots — no desync, just no extra slots.
• The host clamps every player's upgrade level to its own MaxExtraSlots and pushes the correction out, so a client cannot claim more slots than the host allows.

Cap behaviour

Once you own all 3 upgrades, using another one is blocked and the prop is not consumed — you get an on-screen message and the item stays on the ground for a team-mate who still needs it.

The shop cannot filter per player (the host rolls one shop that everyone sees, which is how vanilla upgrades work too), so this is what stops a maxed player wasting $25K.

Configuration

BepInEx/config/extrainventoryslotupgrade.cfg

There is also an /eis chat command: /eis slots <0-3> and /eis status. Forcing a slot count works only as the host or in solo play, so it cannot be used to hand yourself slots in someone else's lobby.

Known conflicts

Do not run this alongside MoreInventorySlots (nickklmao) or ExtraInventorySlots (DarkSpider) — they do overlapping things and you will get duplicate slots. The mod detects them at startup and logs a loud warning.

Reporting a bug

Set VerboseLogging = true, reproduce the problem, and include BepInEx/LogOutput.log. The mod logs its HUD layout and slot construction in detail, which usually pinpoints the cause immediately.
