Guster Extra Inventory Slot Upgrade

GusterStudios edition.

Adds a pink shop upgrade that grants one additional inventory slot each time it is used, up to six total slots per player.

Features

• The upgrade appears in shops and on the upgrade stand, using a custom pink 4+ box decal.
• Each purchase grants one extra slot; the maximum is six total slots (three vanilla plus three purchased).
• Keys 4, 5, and 6 select the additional slots.
• Slots clone the game's vanilla inventory UI, including item icons, battery and ammo bars, hover animations, and centered layout.
• Upgrade levels synchronize through REPOLib and persist across level transitions, saving/loading, and rejoining.
• Default shop price is $25,000–$30,000; the range can be changed in the BepInEx config.
• Every player in a multiplayer lobby needs the mod. The host controls the upgrade cap.

Keys 5 and 6 overlap with the vanilla emote bindings. Rebind those emotes if needed. Do not install this alongside ExtraInventorySlotUpgrade, MoreInventorySlots, ExtraInventorySlots, or BagExpander.

Dependencies

• BepInExPack 5.4.2305
• REPOLib 4.3.0
• REPOConfig 1.2.7
