Kaucja v3.0.0 – "Unexpected Depths" Changelog

Release Date: [18.06.2026]
Minecraft: 1.20.1
Forge: Latest recommended

✨ New Features

• Bottle Pet Battles – Tame a Recycler Corgi, Trash Panda, or the new Glass Golem, then battle other players’ pets in a turn‑based arena. Each pet has unique moves. Winning earns experience and cash.

• Black Market Auction House – Hidden in the Hacker Den, players can now bid on illegal items (hacking devices, dirty bottles, stolen goods) in timed, blind auctions. Beware: bidding raises Suspicion, and police may raid the house.

• Bottle Weather Machine – A late‑game multiblock structure that lets you change the weather within 128 blocks, using empty bottles as fuel (glass = clear, aluminium = rain, plastic = thunderstorm).

• Insurance Scams – Craft fake Insurance Policies at the Label Forger and sell them to unsuspecting players. If the buyer dies, they get nothing. Report scammers to the police to place a bounty on their head.

• Bottle‑Powered Roller Coaster – New Bottle Track rail type and Launch Ramp. Minecarts go faster, and ramps consume a bottle from the cart’s storage to boost you upward. Build a recycling theme park!

• Possessed Bottles – Rarely, a dirty deposit will spawn a hostile Possessed Bottle instead of a refund. Defeat it for Ghost Glass, used to craft a wall‑piercing Spectre Bottle throwable.

• Recycling Cartography – Craft a Bottle Map that highlights all Deposit Machines, Shops, and trash cans in a 500‑block radius. A Bottle Compass points to the nearest Deposit Machine.

• Bottle Musical Instruments – Play a Glass Bottle Xylophone (pitch changes with liquid level) or an Aluminium Can Drum. Both output redstone note block signals.

• Kaucja Gazette – Every in‑game week you get a newspaper with market prices, top recyclers, seasonal events, wanted posters, and recycling tips. Free subscription, delivered automatically.

• The Infinite Bottle (Mythic Item) – Combine every Kaucja item in a Recycling Nexus (9 Eco‑Beacons) to receive the ultimate endgame relic. It generates one random empty bottle every 10 seconds, is indestructible, and grants the “Bottle God” title.

⚖️ Balance & Gameplay

• Black Market auctions now have a 10% fixer fee; police raids occur if too many dirty deals happen in one village.

• Possessed Bottle spawn chance is very low (0.5%), but increased in the Rustbelt dimension.

• Bottle Weather Machine requires a Nether Star and a Microchip to craft, making it a true late‑game goal.

• The Infinite Bottle ritual consumes every Kaucja item, resetting your collection – the ultimate sacrifice for the ultimate reward.

🎨 Visual & Audio

• New textures for the Pet Arena, Black Market stall, Weather Machine, Bottle Track, Possessed Bottle, and all musical instruments (consistent 512×512 style).

• Unique sounds for pet battle actions, auction bidding, weather machine activation, roller coaster launches, and the Infinite Bottle’s golden particles.

📖 Documentation & Translations

• All ten new features added to the Kaucja Manual and advancement tree.

• Full Polish translations for every new item, block, mob, and GUI element.

🔧 Technical

• Fully backward‑compatible with all previous Kaucja worlds.

• Pet battle system uses a lightweight state machine; no performance impact.

• Black Market Auction House uses a simple blind‑bid protocol over existing network channels.

• No new dependencies; everything runs on the core Forge 1.20.1 environment.

Unexpected Depths brings a playful, mysterious, and deeply social twist to your recycling empire. Build a roller coaster, gamble on the black market, or chase the Infinite Bottle – the choice is yours. Every bottle counts.
