About the Game

We are Aetherion Corporation, the world’s greatest chance, its salvation. Earth is running out of time: no more gas, no more fuel, nothing but wastelands and starving children left in complete darkness.

For years, we’ve been working on an infinite source of energy, project ‘Red Sun’, and now we’re closer than ever. And we need you.

Welcome to Aetherion, please, find your contract details below.

You are to explore the surface of planet 347TH2-Terminus and recover resources essential to completing Project ‘Red Sun’. Proceed with caution, the surface is perilous, and many agents have ventured there, never to return.

Should you succeed, a promotion will welcome you home. Should you fail, you will inspire thousands of future agents to carry on your legacy.

Article 1.2: All combat data will be collected and shared with future agents to increase their chances of survival. The more weapons you deploy, the more foes and unknown threats you encounter, the easier it will be for us to develop upgrades and new gadgets.

Every time you fire a shot, every time you use one of the gadgets we’ve provided, we will be watching. You’ll never be alone down there… We’ve got your back.

Article 2: You will be a proud member of the Crimson Gate, our best space ship. For the duration of your contract, you will be given a bed, a home, and a family. Every crew member stands ready to aid you in your mission, providing knowledge, weapons, gadgets, and any assistance you may require.

And if you do not return, each and every one of them is prepared to take your place and carry on your fight. Be it the engineer, be it the cook, be it every. single. one. until. the. last.

Article 3: Aetherion is the only thing you can trust out there. I will relay our orders, your tasks, your purpose, and the way you must live in order to maximize the mission’s chances of success, and, of course, your own chances of survival.

We… I will be your one and only truth. It is a pleasure to meet you, agent, I am Cora, the on-board AI of The Crimson Gate.

And remember:

“Together, we build a brighter tomorrow.”

The objective remains unchanged: a cold, lifeless expanse, interrupted only by automated hostiles and industrial remnants.Additional environmental expansions are already in preparation.Ballistics & Impact Systems UpdateOur engineering division has implemented foundational upgrades to projectile behavior systems.Operational adjustments include:Improved projectile collision detection protocolsDistinct impact signatures for each projectile and surface materialExpanded particle responses for status effects and restoration eventsThese refinements are designed to enhance combat clarity and prepare the system for future weapon and enemy variants.Note: Collision calibration may still require adjustment for Heavy Gunner units. A corrective hotfix is scheduled.Trap Interaction RefinementField feedback indicated that trap descent events were overly abrupt.A new visual transition protocol has been introduced to smooth the experience while preserving mechanical integrity. Agents are encouraged to report on field performance.Structural CorrectionsThe following system irregularities have been resolved:HUD failing to redeploy after specific cutscenesRusted door control panel in The Wires not responding co...

    Join our Closed Beta!

    Welcome Agents.You may have noticed that the mothership has been silent for the past few weeks regarding your presence at the Crimson Gate. That silence has now been broken, because something big is coming. We have new information regarding your mission on 347TH2-Terminus and Project Red Sun. The last time you checked in, you had access to the state of the planet and the Wires, the first explorable zone. We are now launching our closed beta for FALLENSTAR, granting you new access and tools to progress further on 347TH2-Terminus. Here are the changes you will encounter during your journey down there:A new zone of the planet has become accessible thanks to your last escapade: The Cortex a fortified control hub once used to oversee the plasma reactor and its connection to the power grid. Once a secure facility for engineers and security personnel, it is now overrun by hostile defense systems. Designed to counter large scale attacks, its corrupted AI now targets all intruders without hesitation. Expect a brutal welcome. New enemies have been spotted in the Cortex. Be very careful, as they’re very different from anything you’ve encountered so far:Needle Drone: robotic flying enemy that fires bolts that cause bleed damage Scorch Spider: robotic spider that crawls on walls and ceilings and fires lasers that inflict burn damage Trooper Bots: large robots that move slow but hurt a lot Auto Turret: rapid firing turret that shoots any organic creature on site Missile Battery: same as the turret except the projectiles explodeYou can join this beta by entering the Aetherion Discord server. You may access the portal by scanning the QR code below or clicking on this link.May you uncover the answers we seek, Agent.

    Dev Diary #1: Meet FALLENSTAR's creator!

    Hello Agents,Welcome to our very first DEV Diary, a series where we shine a light on the people working behind the scenes to bring FALLENSTAR to life.Today, we’re starting with Ben, founder of NebulaVoid Interactive and the mind behind FALLENSTAR. But before we begin, feel free to join our Discord to stay updated and take part in future events: https://discord.gg/vC3nmDXxejA few words to beginAbout Me: I'm Ben, owner of NebulaVoid Interactive and creator of FALLENSTAR. I'm (hopefully) in the process of shifting my career from software engineering to full-time game development. The corporate dystopia in FALLENSTAR is inspired by my own experience and disillusionment with American corporate culture, which gives the game a very personal, unique edge.What I’m Working On: Right now I’m focused on programming, design, production, and everything in between. I am building systems involving random level generation, enemy AI, and combat balance. I also find time for refining game feel, and writing the world itself. I started this project on my own, and I’m committed to ensuring it grows into the kind of experience players expect and deserve.My Vision for FALLENSTAR“I want the world of FALLENSTAR to feel dangerous, but I also want players to feel like a threat themselves. The combat is meant to be challenging and unforgiving, the exploration rewarding, and the lore rich. My goal is to fully immerse players in the world my team and I are building.”Here's a short video to present myself:
