Built using Unreal Engine 5, Mother Machine is a roguelike, featuring mutant gremlins, their defective robotic mother, and a new frontier in procedurally-generated co-op action gameplay

Players control one of many grotesquely adorable “chaos gremlins” who are endlessly sent to death, then revived by their malfunctioning robot mother in search of resources, technology, and the answers to the planet’s darkest mysteries.

Set thousands of years in the future, Mother Machine takes place on a distant planet once colonized by humans but since abandoned. Left behind by her creators, an Artificial Intelligence faced a problem: without a purpose, she needed to find a way to protect her digital mind from breaking under the burden of being forever alone. Her solution was to create a creature that she could take care of.

True rascals, with an affinity for mischief and chaos, these little gremlins were bioengineered by their mother to withstand and survive a harsh alien environment. 3D-printed from organic filament by their godlike Mother Machine, these creatures are tasked to collect and explore a vast cave network of a mysterious alien planet, brimming with biodiversity and peculiar life-forms — but the further the gremlins venture, the more they find out about the dark secrets of the planet’s history, and the true ambitions of their mechanical mother.

Maschinen-Mensch announced that the Open Beta Playtest for Mother Machine is now accessible for all players on Steam!

Beginning on November 22nd at 10:30am CET and lasting until the same time on November 25th, a work-in-progress build of the game will be made open to the public for the purposes of optimizing and fine-tuning core mechanics and online multiplayer functionality.

Players interested in participating in the playtest can do so by visiting the game’s Steam page.

Included in this playtest will be a Play with the Devs Livestream beginning at 6pm CET / 12pm ET / 9am PT and hosted on the game’s Steam page, where fans can chat with the developers behind the game, ask questions, and even provide feedback and suggestions on what they’d love to see from Mother Machine in the future! As well, Twitch Streamers can enable Drops so that their viewers can get the exclusive Gremlin Constructor Hat item. All players are encouraged to record and/or stream their gameplay footage, and are free to publish any other forms of content.

This Open Beta Playtest will feature multiple levels for players to explore, each of which is set across a different biome, as well as a central Hub to connect with other players and level up their gremlin of choice. There will be limited customization options available, but necessarily won’t carry over for players who return for future playtests.

This playtest will offer several new features not available to participants of past playtests, including mouse & keyboard support, new UI animations & icons, enhanced visual and audio effects, and more! This playtest will have no player cap, and will be available on Steam.
