Overview

About this game

Welcome to the Particle Box room, intern #6407. Your job is to generate electricity using a newly developed Particle Box, which consists of particle-emitting modules in a 3D grid. Combine the effects of 35+ unique modules to create synergies, begin chain reactions, and narrowly pass your session target.

In this incremental roguelite, you'll have to learn to adapt to modules that are available to you in the shop, and strategize to turn a given run's probability into profitability. Don't worry if you fail at first though – you'll be able to unlock new modules to progress between runs. Once you get the hang of getting your B-Type Deterministic Amplifier and TS-47 Laser Ring to endlessly energize your Nondeterministic Fission Core, you'll be generating 10^35+ g-particles in no time!
