About the Game
BASE BUILDING
Your task is to construct a two-way rift back to Earth. It is a very complex invention and requires enormous amounts of energy. Simple solar collectors and a few tons of steel will not be enough. You will need to build up a complex chain of mines, refineries, powerplants and research facilities to complete this mission.
DEFENSE
Your presence on this planet will not go unnoticed. As you build up your industry and disrupt the natural order, the world will start seeing you as a threat. Build up your defenses. Construct walls, barriers and defense towers as the attacks get stronger with every passing day. You will face thousands of hostile creatures trying to eliminate your presence.
EXPLORATION
Galatea 37 is an unknown planet in the Sycorax belt of the Milky Way galaxy. Long distance surveys detected that it is inhabitable and perfect for colonization. The planet is full of rare minerals and substances that can be found in various locations around the globe. Varied biomes can surprise you with unknown fauna and flora as well as harsh weather conditions. Construct local outposts in resource-rich locations that will transport the required resources using rift technology.
CAMPAIGN MODE
You play the role of captain Ashley S. Nowak - you are the Riftbreaker, an elite scientist/commando inside a powerful Mecha-Suit. Enter a one-way portal to Galatea 37, a distant planet at the far reaches of the Milky Way Galaxy, with the purpose of building up a base that will allow travel back to Earth and further colonization. Ashley's Mecha-suit, which she calls "Mr. Riggs", can withstand the harshest environmental conditions and has a full range of equipment for base construction, resource extraction, gathering specimens and of course - combat. It is capable of traveling through rifts that connect space across vast distances.
Take on an epic journey across all the different biomes of Galatea 37. You will establish multiple persistent bases across the globe that will fuel your economy. Research alien substances and lifeforms, as well as fight hordes of alien creatures, clearly not happy with your interference in the natural order of the planet. The campaign spans multiple hours and offers a remarkable degree of freedom in a super detailed, procedurally generated world. You can decide on the order of your priorities and what technologies you want to use. You’re the only human there, after all.
SURVIVAL MODE
Your mission is to survive a set amount of time, fighting off increasingly difficult waves of enemy creatures. Each mission in the game is randomized, offering nearly endless replayability.
HANDCRAFTED SOLO AND CO-OP EXPERIENCES
The Riftbreaker can be played solo or together in a group of up to 4 friends in Online Co-Op. Every game mode and each mission was specifically balanced to be enjoyed in single or multiplayer mode. The game includes a built-in server browser and a dedicated server mode. It can be played online or through a local LAN connection, entirely offline.
SANDBOX
If intense fight for survival is not your thing either, then try out the Sandbox mode, where we give you control over the entire game – including resources, enemy spawns, and weather conditions.
CUSTOMIZE YOUR GAMEPLAY
The Riftbreaker’s gameplay can be customized to fit your playstyle. You can change the frequency of enemy attacks as well as their strength and numbers, resource abundance, weather events, enemy damage, and tons of other settings. There are also multiple difficulty presets to suit the needs of both hardcore strategy players as well as those that want a laid-back base-building experience.
COMMUNITY DRIVEN DEVELOPMENT
The Riftbreaker’s development is continuously fueled by its welcoming community. The game has received years of support after its original release and is continuously expanded thanks to community suggestions and direct contributions. The game has a very open content structure and comes with a built-in set of modding tools, dedicated Steam Workshop integration, and a Mod Manager.

Expect more fixes to arrive next week.

Hello Riftbreakers!
After a period of testing on the experimental branch and positive results, we are publishing the last week's hotfix to the default branch of The Riftbreaker.
The new patch should fix all the maps and objectives where the game flow got stuck, right after loading your save file. No tricks necessary - it should just work.
This build contains no other changes.
Once again, please accept our apologies for causing this mess in the first place. We hope that this patch will help you progress with your Campaigns as expected. If you still encounter issues, please do not hesitate to contact us here, on the Steam Forum, or on our Discord at https://www.discord.gg/exorstudios

Hello Riftbreakers!
We have just pushed a hotfix to remedy the issue that caused players to be unable to progress in many areas of the Campaign mode - scouting missions, various areas in the DLC missions, and others. We are very sorry for any problems we have caused.
This patch will not help if you have reached a point where the campaign has gotten stuck. We will develop a patch that will push your campaign flow further, but we need until tomorrow to get it done. In the meantime, loading an earlier save file should allow you to proceed without issues.
Additionally, we have received reports from users that Windows Defender throws a false positive, preventing them from accessing their save files. These are the troubleshooting steps that helped them:
https://steamcommunity.com/app/780310/discussions/0/598536531263685649/
Our investigation shows that this problem occurs when you have the 'Controlled Folder Access' feature enabled in Windows Defender Ransomware Protection. By default, it protects the Documents folder. If you have it enabled, you can probably see a lot of attempts by our game to write to your disk by checking the 'Protection History' section. You can whitelist the app from there.
If you encountered this issue, please make sure The Riftbreaker is whitelisted in your Windows Defender app.
Once again, please accept our sincere apologies for any problems caused.
