- Hyperspace Deck Command Launched! - 8 October 2025
Hey There Hyperspace FansSleeper Games’ 4th release is here! Hyperspace Deck Command is a deck building rogue-lite that takes place in the hyperspace universe, millennia after the previous games. You’ll assemble a massive space force from unit and tech cards, which you then deploy in lane-based battles against an enigmatic opponent from outside the galaxy. During battles you’ll always need to think ahead, since units in HDC operate on individual turn timers and every card you play brings them closer to carrying out their next action.The game also features a flexible dual-use status effect system where each effect works differently depending on if it is used on allies or enemies. Fuel can accelerate your own units, or set the enemy on fire. Shields can block damage on your ships, or contain enemy weapons to negate damage and status application alike. Fighter craft can intercept hostile b…

- Hyperspace Deck Command Demo Released! - 25 March 2024
https://www.youtube.com/watch?v=aBZprZeheIE Hi there Sleeper Games crowd. To be a part of Steam’s ongoing Deckbuilder Fest I put together an early experimental demo for Hyperspace Deck Command, my upcoming sci-fi deckbuilding roguelite that will also be the third entry in the Hyperspace Anthology. You can try it right now here on Steam. The game has only been in development for 5 months now, so this is still just a small part of what is yet to come. In the demo you can fight your way through 5 different simulation encounters using a randomized starter deck, culminating in an super long final battle hat requires a powerful fleet and proper mastery of the game’s fresh dual-use status effect system. A lot of main features (starting deck selection, card upgrades, stores) are still missing though, but I hope you get a few hours of fun out of it regardless. I'm sure it makes up for the lack o…
- Abandoned Prototypes + Hyperspace Anthology Vol 3 Announcement Soon - 15 January 2024
After spending some time on post-launch content for Swirl W@tch and Red Tether last year I have now finally settled on what Hyperspace Anthology Vol 3 will become. The game will be official announced very soon. In the process of getting there I produced yet another (probably to be abandoned) prototype that didn’t make the cut. I also revised a lot of older prototypes and small experiments that didn’t go anywhere either. Looking over all this stuff was weird but also fun and I now I really just want to dump all those gifs on you too. So join me on a journey through roughly 3 years of my life that went into making game content that will likely never be released. ¯\_(ツ)_/¯ It’s hard for me to not see this as wasted time, but then again many things you’ll see here made it into other games in some way or form, so it's not all lost. Hyperspace Admirals was planned to be a tactical captain sim…

- Red Tether 1.3 Harpoon Hunt Is Here! - 3 October 2023
https://i.imgur.com/MAj3Ubp.gif Attention all RTP members. It appears another branch of GC's unofficial clandestine service has infiltrated Con space alongside the Red Tether Protocol. So far their activities have gone unnoticed by both us and the Contempter, but now the program has entered its main phase: Millions of “Void-Fabricated Interstellar Subversion Helpers”, or V-FISH have hatched all across the Contempter’s systems. These bio-mechanical agents are now attempting to cause chaos and hinder fleet movements. https://i.imgur.com/4p4zNPB.png It is unclear whether the V-FISH will have any noticeable impact on our mission, we'll need to study them to learn what they can even do. The fish creatures are technically on our side, but they are not particularly smart agents and will attempt to evade capture by us. You’ll need to hit them with a harpoon, reel them in and tire them out befor…

- Fishy Encounters: ---Red---Tether--> 1.3 Harpoon Hunt Is Approaching! - 23 September 2023
https://i.imgur.com/riBy3Rv.gif Red Tether’s next content update is in the works! This one will focus on the often teased harpoon fishing system. On rare occasion you’ll encounter bio-mechancanical fish-creatures in-between waves. Harpoon them to initiate a high speed chase! Drag them down to wear them out enough and you might just be able to reach and catch them, granting unique new upgrades to your ship. There will be a whole bunch of creatures to catch, with many only being found in specific zones. https://i.imgur.com/cbU1SZ7.png Due to the nature of the base game, the fishing system integrates completely seamlessly. You wouldn’t even call this a minigame I think. A ton of upgrades that help with tether combat will also benefit you when harpoon-fishing. Fishing opportunities are fairly rare and generally you will only get one or two during a run. So since this update focuses on a not…
