The Riftbreaker's World Expansion IV update launches today, March 5th, 2026, as a free content update on Steam, Epic Games Store, GOG, PlayStation Store, and Microsoft Store. Alongside the update, the game receives its biggest discount to date at 67% off on Steam, running through March 26th, with a free weekend to let new players try before they buy.
The Riftbreaker asks you to build, defend, and expand across a hostile alien world, all while piloting a Mecha-Suit capable of tearing through waves of creatures and constructing entire industrial chains on the fly. You gather resources, refine them, research new technology, and erect defenses as the planet pushes back harder with every structure you place. Walls, barriers, and defense towers become essential as attacks escalate, throwing thousands of hostile creatures at your base in response to your growing industrial footprint. The loop tightens as you go: expanding your operation means disrupting the natural order further, which means fiercer resistance, which means you need better defenses, which means more resources, which means more expansion. You can be managing power grids and supply chains one moment and hacking through alien fauna with Mr. Riggs' combat systems the next, the game keeping both halves of its identity, the builder and the brawler, running in parallel. You can tackle all of it solo or with up to four players in co-op.
That loop plays out across Galatea 37, a distant planet in the Sycorax belt of the Milky Way. Its biomes range from lush and volatile to frozen and barren, each hiding rare minerals and hostile wildlife adapted to local conditions. You construct outposts in resource-rich locations and link them using rift technology, turning the planet's geography into a logistics puzzle layered on top of the combat.
You play as Captain Ashley S. Nowak, an elite scientist and commando who stepped through a one-way portal to Galatea 37 with a single objective: build a two-way rift back to Earth to enable colonization. Her Mecha-Suit, which she calls Mr. Riggs, handles everything from base construction and resource extraction to specimen gathering and combat.
World Expansion IV's headline addition is the Open Campaign mode, built specifically for experienced players who want the safety nets removed. Instead of following the story's prescribed path, you choose your starting biome from every Galatean zone available in the game and decide where to go next based on your own economic and technological needs. Ashley and Mr. Riggs stay quiet in this mode, offering no commentary on your progress and no hints about what to do next. It's a mode that trusts you to read the systems and chart your own course, changing the pacing considerably. The campaign normally guides you through biomes in a deliberate order, teaching you the planet's rules as you go. Open Campaign hands you the full map and lets you figure out the sequencing yourself. Like any other game mode in The Riftbreaker, you can either try beating it solo or with a group of up to four players.
The update also introduces the Cryo Fields, a permanently frozen biome covered in ice and frost. It brings a new resource called Supercoolant and a population of Galatean creatures that have adapted to the cold in ways that demand new strategies. New buildings and defensive towers round out the additions, expanding the construction options available across all modes.
The Riftbreaker, developed by Exor Studios out of Szczecin, Poland, is available now on PC, PlayStation 5, and Xbox Series X|S. The studio's roots trace back to a modding group formed in 2003, and their first standalone game, Zombie Driver, sold over a million copies. The Riftbreaker builds on that foundation with a game where the tension between construction and destruction never lets up, where every new refinery or power plant you place is both progress toward your goal and an invitation for the planet to hit harder.
