[1.20.1-2.1.0] - 15/10/2026

The Null Void is now a more dangerous place to explore, with new creatures, prison structures and Plumber gear.

Added

• Null Void prisoners hunt in packs, flank players, flee when badly hurt and sometimes fight each other.
• Null Guardians patrol the islands and pull targets in with a tractor beam. Lepidopterran scouts dive-bomb and spit slowing slime.
• Floating prison blocks hold prisoner spawners, a prison warden and a key-locked loot vault. Wrecked Plumber outposts contain supply chests.
• Taydenite ore and storage blocks, guardian membranes, prisoner cuffs, cell keys and Plumber loot.
• A Plumber blaster, Null Void glider and full Plumber armour set, with recipes and set bonuses.
• Flight animations: Heatblast flies like a rocket with a flame trail, Stinkfly beats his wings, Ghostfreak drifts.
• XLR8 has a sprint animation (leaned forward, legs a blur, arms swept back, tail streaming) with a blue speed streak and kicked-up dust behind him. Sprinting fast enough, he runs across water; slow down or sneak and he drops in.
• Transformed camera height now follows each alien's hitbox. Every transformation has a green particle burst and a third-person morph; reverts use green or red bursts.
• Holding the power key repeats powers when they are ready. Alien powers have tuned cooldowns and a cooldown bar.
• The Null Void Projector opens a walkable portal that pulls in nearby creatures and items, with arrival guidance for the Null Void's floating islands.
• Vilgax, Kraab, Zs'Skayr and the prison warden speak to nearby players during fights.
• The Plumber blaster fires a fixed-damage energy bolt instead of an arrow.
• Prison cells hold loot chests. The Prison Vault now gives diamonds, more taydenite, Null Crystals and Infinitum, two Plumber armour pieces, a blaster or glider, and golden apples (sometimes an enchanted one).
• Your first trip to the Null Void hands you a Null Void Glider (in a chest beside you if your inventory is full).
• Beating the prison warden tells nearby players to use its Cell Key on the vault. Every Null Void arrival shows how to get home (use the projector again), and the guide book explains it.

Changed

• Stinkfly's flying wingbeat is slower and wider, so the flap is visible.
• The Null Void landing pad is lit by sea lanterns at its corners instead of a tall end-rod pillar.
• Armour and tool stats follow the ore ladder. Starter sets are around iron, Legendary and Black Diamond around diamond, Infinitum around netherite; no armour piece gives more than 8 points. Black Diamond tools are diamond tier, Infinitum and Imperium netherite tier.

Fixed

• The Null Void had no islands between about 150 and 1,000 blocks from its centre (it reused the End's island layout), and the projector ignored islands in chunks that hadn't loaded yet, so most trips ended on the emergency pad. The Null Void now has its own floating islands everywhere, and arrivals land on the nearest one. Chunks generated before this update stay empty, so explore new areas or use a new world.
• The "nearest island" hint pointed at the emergency pad itself ("about 0 blocks").
• Flying mobs (Zs'Skayr, Vilgax drones, Null Guardians, Lepidopterrans) crashed the game when they took off.
• Leggings gave more armour than chestplates (values were in the wrong slot order).
• Mod armour wore out about twice as fast as vanilla armour of the same tier.
• Heatblast fireballs now damage fire-immune bosses, and Plumber armour resolves its namespaced textures.
• The power key (V) stopped working after dying or changing dimension, and the transformation animation could stick after changing dimension as an alien.
