We had a lot of ambitious ideas for this one, which weve added along with plenty of community requested features. Read on to find out whats coming your way early next year.\n\nhttps://www.youtube.com/watch?v=odARerNhDZU\n\n
New Biome Beyond the Passage!
\nThose of you who have made it to the outermost regions of the underground might have thought that youd reached the end of the world. Well, thats the thing about ancient underground cavernsjust when you think youve explored everything, something new and exciting crops up on the horizon! \n\nWelcome to Breakers Reach. This brand-new biome is bristling with untold secrets and inorganic life. Navigating this mechanical world wont be easy, with Chargers, Patrollers, and Swarmers protecting the valuable resources within, but itll be worth the challenge for access to new tools, weapons, gear sets, and crafting materials!\n\nMeet S.A.H.A.B.A.R
\nWe werent about to reveal a whole new biome without giving you a cool new boss and mysterious dungeon for you to explore. If youve ever wanted to re-create your favourite anime scenes and battle a GIGANTIC robot, then youre in luck! S.A.H.A.B.A.R is a machine straight out of your nightmares with laser-targeted energy beams and special abilities thatll put your timing to the test! \n\nAutomation for the Nation
\nWith a machinery-focused new biome and more robots than you can shake a Solarite Sword at, youre gonna have your hands full of mechanical parts. If only there were new and exciting automation features to craft with themIntroducing the Advanced Automation Table, an all-new workbench thats set to make your lives easier from here on out!\n\nWhether youre looking to streamline gardening with the new Seed Extractor and Robot Farm Arm, or youre ready for new and improved salvaging and item disposal, this handy workbench has a whole host of new crafting recipes just waiting to be uncovered. There are oodles of new automation systems and electronics coming to Void & Voltage, such as new generators, critter catchers, proximity sensors, and more!\n\nFire in the Hole!
\nYou can expect lots of new gear with this update, Explorers, including miniguns, mortars, grenades, and even remote detonators. Oh, and did we mention the new flamethrower? Youll light up the underground with this handheld weaponjust watch out for oil barrels, rumour has it they can get a little explode-y around fire. Were also adding a bunch of new decorative items, armour sets, new off-hand items and accessories, and an all-new minion and tome. We could spend forever listing all the new additions, but we think its much more fun to go out and discover them for yourselves! Be careful, though we werent kidding about the oil.\n\n
\n\nVoid Sub-Biome
\nTheres something strange occurring in the underground where the very fabric of spacetime seems to warp and tear, creating an otherworldly new sub-biome filled with threatening variations on some familiar enemies. Expect to cross paths with Void Larvae (emerging from Void Coccoons!), Void Cavelings, Void Shaman, and Void Brutes! These enemy variants use a never-seen-before combat mechanic, allowing them to make special attacks such as explosive flames, spinning arcane beams, and lightning orbs! Were very keen to hear what you think of this all-new system and if it is something youd like us to continue developing. Keep your wits about you, Explorers. Standard enemy variants arent the only things that have crossed the voidbeware the Void Hydra!\n\n
\n\nAnd More
\nEcho maps that are used to locate important areas within the world (we know youve been asking for this one!), 6 new crafting statues with waypoints, a whole host of new scenes, new achievements, new paintable items, minion improvements, the ability to break previously indestructible itemsthe list goes on. Well share the full patch notes when the update launches on January 28th 2026!\n\nWe cant wait to hear what you think of Void & Voltage when it launches on January 28th.
