- Co-op survival shooter Ammo and Oxygen feels like Helldivers with a horror twist - 7 September 2025
I've been a big Helldivers fan since the days of the original. While Arrowhead has done a phenomenal job of converting its top-down co-op shooter into the full-featured, third-person Helldivers 2, I still firmly believe there's space for the classic perspective. It worked just as well in Valve's Alien Swarm, and now the latest take on the format has arrived courtesy of indie team Juvty Worlds. Ammo and Oxygen feels like a fusion of old-school Helldivers and the survival horror of Dead Space. Nearly one year since it first launched in early access, Ammo and Oxygen 1.0 is here, and you can grab it at a discount if you're quick. Read the rest of the story...

- What We Are Working On: Destructible Objects and Secret Rooms - 12 March 2025
Hello! Are there any other survivors here? Thank you for your support and feedback. We are working on adding destructible objects to the game. Now, all levels will feature interactions with the environment that impact gameplay: - Monster eggs. These can be both a source of extra DNA and trouble (toxic clouds, monster spawns). - Boxes that may contain loot. - Explosive barrels that deal damage to both enemies and characters. - Barrels with thick liquid that slow down movement. In addition to the above, some passages will also be destructible. For example, to access Secret Rooms! You will be able to identify a secret room by cracks in the wall, and if you break it, you will enter a small area with extra loot. Thank you! I hope this is not cryostasis.

- Public testing - Experimental changes to melee combat - 14 November 2024
Hello! Are there any other survivors here? Thank you for your support and feedback. We are working on update 0.8, which will include mini-dungeons in the Swamps, new power-ups and equipment, a variety of monsters in the lairs, and many other improvements. We are releasing a test version to gather feedback on the changes to melee combat. What has changed: Movement is blocked during attacks, but you can change the direction of the attack after swinging. To compensate for the immobility, attacks occur more frequently, the hit area has been increased, and it responds better to moving targets. We want to hear your opinion on these experimental changes. How to test: Select Ammo and Oxygen in your Steam library. Right-click -> Properties -> Betas -> Switch to development at the top right (you can switch back here whenever you want to use the main version of the game). We recommend testing in E…
- I wanted to review my game, but I found out Steam has no such feature - 7 November 2024
I have always loved roguelikes like TBOI, survivals like Don't Starve (both especially in couch co-op with my wife) and hardcore top-down shooters like Hotline Miami. Finally, I have combined these elements in our game. It's not perfect, and there’s still a lot to improve, fix, and add, but we are ready to work even harder after the game's release. We hope you will understand and help make this game much bigger and better! P.S. My mom also bought this game and said she would be reading the reviews. Please don't write nasty things here — if you really want to, you can message me privately. Pros: + At some point during development, I became genuinely interested in play new and new runs, though I was afraid that our game might turn out to be boring. Cons: - I want much more content. - Bugs don't want to fix themselves.
