Nuclei
SteamNuclei is a puzzle-platform video game in which you control a robot that must escape from the factory where it was created after suffering a short circuit in the production line. To do this, it will use various components and objects that will grant it multiple skills, necessary to overcome the obstacles that it will encounter in its adventure designed to also be enjoyed in cooperative multiplayer format.
In Nuclei you'll find yourself controlling the spherical and defective nucleus of a friendly robot all alone in the depths of a colossal and collapsing factory... or maybe not. Other players will be able to join in this adventure and cooperate in finding your way out in one piece... Or that would be the case if our robot wasn't modular.
From electromagnetic tools to codification modules and with the help of different sets of legs, your character will be granted new abilites that will challenge your puzzle solving skills, but only if you still have them attached to your robot! With up to four components at a time and in an infinite number of possible combinations, the complexity of the puzzles ahead will increase gradually as you travese your way through the Factory.
A gargantuan structure with the purpose of mass production of robots and new tech, it serves both as the birth place and a prison for Nuclei's characters. You'll be forced to navigate through its sectors and sections in the form of different sets of levels that will add and require new tools and abilities in the search of a way to free your character and avoid its destiny guided by the Trader.
An anomaly such as your character, a robot with enough knowledge to help you out. It'll be your guide through the complex, in exchange of completing its never ending requests. A fair trade for survival will be your only option out there. If you complete some extra requests, he may even be able to tweak some components and allow your robot to use higher-end tools.
