Idle sci-fi RPG where combat actually matters. Crash-landed on an alien world, you rebuild through five skills, melee/ranged/void-magic combat, and a server-wide world boss. Progress keeps going while you're AFK. Solo, co-op, or faction raids. Free to play. No pay-to-win.
Revenue comes from in-game items and microtransactions, which our price-based model doesn't estimate. The player count below is how many people own it, not what they spent.
About
You crash-landed on an alien world. The ship is scrap, the planet is hostile, and progress doesn't stop when you step away. Lost Vessel is a sci-fi idle RPG with real combat, deep crafting, and a slow climb back toward the stars - playable in thirty-second bursts or five-hour grinds. Free to play, no pay-to-win, ever.
Five skills pull you back from zero: salvage the wreckage, mine the planet, harvest alien flora, fabricate weapons and armor, analyze every sample for the next tier of everything. Each skill compounds the others - endgame materials require components from all five.
A melee / ranged / void-magic triangle where every enemy has a weakness. Crits, armor pierce, dodges, reflects, instant kills on legendary gear. Weapons degrade with use and break permanently if you let them. Fight through zones with escalating difficulty all the way to a dimensional rift at the endgame.
Equipment starts common and works up through rare, epic, and legendary at the Forge. Legendaries aren't just bigger numbers - 5% instant-kill, 25% skill-speed auras, damage reflection. Loadouts let you switch a combat kit, a gathering kit, and a backup with one tap. Durability matters. Repair matters. Choices matter.
Assemble I.D.L.E. from parts and you get a second skill queue running in parallel. He's sarcastic, he complains constantly, and he runs on Voidshine - a cross-skill endgame fuel that needs materials from combat, biology, and fabrication. Keep him fed and he grinds while you sleep.
The Nexus Drift is the co-op hub: 2-4 player expeditions, a server-wide world boss, and specialist jobs that pay weekly tokens. Raiders is the PvP side: pick a faction, raid other players, defend your colony, fight for territory. Both are completely optional - solo players lose nothing.
Offline progression is genuinely idle - skills work while the browser or Steam client is closed. A 17-track mastery system grants permanent passive bonuses every time you hit a milestone. Ship augments are a 110-level talent tree for fine-tuning your build. No energy timers, no stamina bars, no premium currency. Just progression.
Optional cosmetic supporter packs let you back the game and show off - exclusive titles, name effects, and profile flair. Cosmetic only, never power, never an advantage.

A well made and presented idle game with lots of content. Reaching prestige seems to take well over a month. I started playing in browser before migrating to Steam so after a month I'm at level 60 and prestige is at level 100. Just hoping there's enough content to keep me interested for the remaining levels. Feedback: Sound effects are atrocious compared to the otherwise slick visuals. I'm playing with the game muted because the sounds are so obviously from some free asset pack. The research complete sfx is probably the worst and plays frequently in combat for some reason. Some sounds don't fit the sci-fi theme at all. It just needs a complete overhaul. The UI looks good with a consistent theme. There are a bunch of stuff that is not really used though, so a setting to customize which buttons to show would be great. Like for instance I have no use for the Roadmap, Tools, Voidhaven buttons which are just cluttering up the space. The most urgent UI fix I'd like to see is to reduce the flashing in the message field at the bottom. Once again, I have no use for "Galaxy" and would like to have a setting to display only tabs I care about. Please remove the flashing and just keep the notification dot if you must.

Не работает. В общем, это, по сути, браузерная ММО, которая заблокирована не то для РФ, не то в РФ.
nice
Great game for a people who loves idle grind games I LOVE IT!
Lost Vessel "Idle sci-fi RPG where combat actually matters" and for sure it does. I do like the game and it is still fairly new and growing. I don't know much about the dev however seems cool enough being in chat and updating and talking with the game players. I do suggest at least giving the game a try. It's not for everyone of course. I tend to run 24/7 unless updates, power loss or internet issues causes me to be offline. There are reviews I've seen with less than an hour and some less than a day. I will never trust or believe anyone can write a decent review of something with next to 0 time in playing the game. Do I have some cons about the game? Yes I do. Biggest issue for me is the codex. Yes this game has 1 however I find it next to useless. First I will start how it works. You open the codex and you have to scroll to the right to see things. No issues in doing that however you click on something and that scroll bar jumps all the way back to the left. Bad design I guess but could be fixed by the dev at any time as updates and such keeps rolling out. The worse part of the codex is like the weapons and armor. Great it gives some details about what you are looking at but it lacks so much. Lets use something simple the fracture blade weapon. It will link you to the page if you click to where to forge it however the codex gives no info about how to make it or how much of the stuff needed to make it. I have to make my own excel sheet to track what is needed and how much is needed to make it and then if you wish to upgrade it takes 4 and then upgrade it again takes another 4 all the while having to keep track myself on what and how much is needed to do so. So why even have a codex if you have to make your own spreadsheets to keep track of these things? Yes I still suggest the game and like the game. There is always room for improvement in just about everything and I know that. PVP is raiders by the way it looks. I joined only to see what it looked like. You can leave and must wait 7 days before you can do anything with it again. I am fine with that as I think this section is more of end game play. I was not and still currently not ready for all that as of yet. Time I waited to post review was over 160 hours which running 24/7 is only just over a week. I am still very new in the game and still low level as it goes but still growing. The store page says idle however do be careful in doing so. Some actions is free to do however as you keep moving on with upgrading and doing things the actions cost. If you pick to make lets say iron plate you will need iron ore and running out while you are away or sleeping and such you do nothing. Fighting your gear has durability and your own HP as well. Don't let your gear or hp die is what I am saying lol. You may like this game and you may hate this game. It all depends on you and your game style. I do suggest giving it over 24 hours at least to know if not even a week. There is still idle things to do so yeah it can get kinda boring after a bit but idle games aren't meant to be beaten or make top number 1 in a day with doing next to nothing. Also seen some say you get a robot called I.D.L.E. which takes a fuel which would be fine except you either have to get from crates or looks like to join raiders to get 1 thing needed to make it yourself. This makes the robot end game style and mostly useless for a good while.
Lost Vessel is a pretty good idle game. It's grown on me rather quickly and I can see myself sticking around. The UI is a little intimidating at first but the in-game guides and codex are comprehensive enough that I never felt lost for long. There's always a variety of tasks to perform, unlike some other idles where it's just "let combat run." There's also a live in-game chat and the community's been very welcoming and supportive to new blood. The developer pops in almost every day to hang out, and I love seeing the attention he gives to his players. Also, I've got a potato PC but the game still runs pretty well even when I have it on the background, unlike some other idle games of this type. If I had a gripe I wish that you could queue up different tasks like "Mine X platinum then Craft Y base plates" instead of setting a single task to run until you log back in. But I don't find that a big deal (yet).
Only played two hours, but it feels like a mobile game. It lacks the consistent dopamine that I need for PC idle/incremental games. Nothing particularly wrong with it, it's just on the wrong platform. Might be viable if you're looking for something to have on a third monitor while playing another game and watching a show, I guess?
this game scratches alot of itches for an idle game.
After playing for 6 days this isnt a IDLE player game it is a constant check stuff still needs to be done like resource gathering, this makes this game super boring and super slow, I laugh at the fools paying $50 for a founder role with no benefits. IDLE Itself is slow and useless and needs better or faster speed to be useless from talking to others in chat they all agree its better not to create the idle robot as its useless.
