Climb together or fall as one. SunderBound is a 2-player co-op top-down shooter with roguelite progression and tactical elements, set in a decaying dieselpunk world shattered by a failed weather weapon. With tech fried and time short, all that’s left is the climb one brutal floor at a time.

You play as two rebels fighting their way through Haven: a dystopian mega-structure ruled by a godlike tyrant known only as The Minister. Each level hits differently, throws harder enemies, deadlier traps, and pushes tougher decisions. Whether you team up with a friend or roll solo with a smart companion, you’ll need to cover each other, sync perks, and time every push to survive.

Every room’s a test. Every upgrade’s earned. You’re here to survive the world. And maybe, break it a little on the way up.

Kipi Interactive is thrilled to announce the launch of the public playtest for SunderBound, a co-op top-down shooter with roguelite progression, coming to PC via Steam and the Epic Games Store in 2026. Starting today, players can join the playtest by requesting access directly on Steam.

Players participating in the playtest are encouraged to share their feedback with the development team on the official SunderBound Discord server, helping shape the game’s final experience ahead of launch. The development team plans to update the playtest over the coming months, adding new content and improvements based on player feedback.

Q: When will I receive access to the game?

A: We will allow the first wave of players to access the game as soon as this week, and will allow additional waves of players every update cycle.

Q: There will be updates?

A: Yes, we commit to updating the playtest build every two weeks to adjust balance, add bugfixes, and optimize performance. (so we will allow a new wave of playtesters every two weeks). Additionally, we commit to at least two larger content patches that will add new enemies and other goodies ;)

Q: For how long will the playtest be available?

A: For as long as we feel that we are getting actionable feedback from you, the players. That means at least two months. After that, if we still need to test out various features of the game, we may keep it open for longer; otherwise, we will close down the playtest to prepare for a demo release.

Q: How can I provide feedback?

A: Please join our Discord server if you haven't already. There, you will be able to write down your thoughts, report bugs, and find buddies to play co-op with. We will also be posting bi-weekly (so, once every two weeks, right?) feedback forms there, where you would be able to go into more detail, if you’d like. You can also post on Steam’s Community Hub - we will also monitor that space closely.

Q: I am a content creator. Can I make content for the game, and discuss it freely online?

A: Absolutely, in fact, we would be very happy if you shared your thoughts. If you are a creator and you would like expedited access to the playtest, do reach out to us on Discord, and we will consider providing one for you.

Important notice: SunderBound is a project that is still under development. This means that there is a lot of missing content, and you may experience bugs, glitches, and/or inconsistency in gameplay. This is a large part of this playtest, and we ask you for your patience if you experience them, and for your cooperation in reporting these issues on our Discord server, or in the feedback forms that the team will share there.

Thank you very much for your interest in SunderBound and we sincerely hope you enjoy the playtest. See you in Haven!

Key Features:

• Built for Two: SunderBound is a 2-player co-op top-down shooter with roguelite progression and tactical elements. It supports local couch co-op, online multiplayer, and solo play with a responsive AI companion.
• Tactical Mayhem: Success requires more than just a quick trigger finger. Cover matters, and timing saves lives. Players must split flanks, sync class abilities, and think on their feet to avoid being overwhelmed by the enemy.
• Procedural Combat Missions: No two missions are the same. Floor layouts, enemy spawns, ambushes, and modifiers evolve with each ascent, ensuring every run is a unique and unpredictable challenge.
• Different Loadout, Different Playstyle: Between missions, players can earn, buy, or craft new gear. Every weapon, perk, and augment sharpens a specific build, allowing for a wide variety of playstyles.
• A Dystopian Tower That Wants You Dead: Battle through flickering factories, hostile medbays, and decayed corporate relics. The world is gritty, hostile, and alive with tension, creating an immersive and dangerous environment.

SunderBound is in development for PC (Steam).
