About LeftUnknown
Live-D Corporation slowly took control of society, enforcing their power through a private army and secret human experiments. Captured and taken to a hidden underground complex, former soldier Marius was subjected to a serum meant to grant eternal life - instead he fell into a coma and awakened ten years later immune to the experiment, only to find the abandoned facility overrun by alien-like creatures created from failed test subjects that spread and destroyed the world. Fight to survive, uncover what happened during those ten years, and find your way back to the surface.
DYNAMIC COMBAT
Combat is intense and grounded, with weapons that feature realistic recoil, bullet spread, and physical impact. Every shot matters, and every encounter can play out differently depending on how you use your tools and surroundings. Grenades can clear groups instantly, while well-timed environmental explosions can save precious ammo.PHYSICS-DRIVEN WORLD
The world of LeftUnknown is built around physics and interactivity. Most objects aren’t just props - they can be moved, thrown, stacked, or used creatively. The environment reacts to your actions, letting you solve problems, fight enemies, or create opportunities using the world itself.SURVIVAL & RESOURCE MANAGEMENT
Survival depends on preparation and smart decision-making. Your inventory has limited space and is weight-based, forcing you to balance firepower with essentials. You’ll need to monitor your health, stamina, and injuries, using med-kits, food, and bandages to stay in fighting condition. Scavenging, buying, and selling items becomes key to long-term survival.ENVIRONMENTAL STORYTELLING
The story unfolds through exploration. Scattered notes and diaries reveal what happened inside the facility, but they also serve a practical purpose. Players who pay attention can discover door codes, and clues that lead to valuable rewards.SANDBOX FREEDOM
LeftUnknown embraces player experimentation. Console commands allow you to spawn objects, enable god mode, or manipulate the world for fun. Whether you want a serious survival experience or a chaotic sandbox playground, the choice is yours.NIGHTMARE MODE
Nightmare Mode offers a pure survival challenge for players who want to test their limits. Face endless waves of enemies and fight to stay alive as long as possible. Every kill earns points, and every second survived pushes your score higher. Compete against friends or players worldwide on the leaderboards and prove how long you can last when the odds never stop stacking against you.*This game is made by a solo developer
What Steam players say
Recent verbatim reviews from Steam — separate from playze.io community reviews below.
The game runs very smoothly and I have had no performance issues at all. It's quite short at this stage (30-60 minutes to beat), but the developer is working on expanding the campaign. There is also the Nightmare Mode which was recently released, similar to COD zombies where you fight off waves of enemies. - Quite good to get into early to beat the scoreboard. If you are into action based FPS games, this is a good one to get for sure. It has similarities to the Half-Life series, which is awesome. The gunplay and physics are also satisfying. I have also spoken with the developer Justonas quite a few times, and I'm honestly excited to see some of the planned features come to fruition.3 found this helpful
More neutral than negative. While price is very low this is more like vertical slice\demo than EA game. Foundation is solid - guns are pretty fun to shoot, movement is good, physics good. But the exploration part is discouraging because of constantly respawning enemies - clear room, turn corner and enemies respawn, and while resources is plentiful backtracking can be a frustrating. Delay when activate your PDA feels not good, items need descriptions, at least smth like - restores health slightly\moderately, stops bleeding etc. Will def follow development progress, because it could be a good game.1 found this helpful
Fun experience with a lot of potential. Has some pretty clever gameplay design elements including physics puzzles. The physics are fun to play around with in general and the gun play is decent as well, especially after the latest updates. Gives off half-life vibes, but with a darker setting. Would say definitely worth checking out and seeing how it grows over time. Even the current progress is mighty impressive considering this is made by a single developer.1 found this helpful
A pleasant, short game with sophisticated physics, which is rare in many large-scale projects. I have some minor complaints about enemies spawning "out of thin air" where they shouldn't be, but otherwise, I HIGHLY RECOMMEND this game for all fans of immersive sims and horrors.1 found this helpful
