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.

Melvor Idle in space (more or less). If you like idle games it's worth a shot. Free to play and the monetization is extremely fair and non-intrusive.
This game isn't something I expected to like playing. I downloaded it and realized it wasn't an interface I expected. I like the layout. I'm not happy about only being able to work one skill without using the I.d.l.e. It's a bit of battling, mining, analytics and strategy. Try it. That's all I can say. I've been recommending people try it since I started. It's definitely worth a look

I've dabbled in Idle games over the years, but this one has to be right up at the top of my list. The fact that it is ZERO P2W is amazing. It helps to keep the sense of a community all working together. The dev, who is doing this all on his lonesome, is continuously adding things into the game. We've had 2 new buildings built entirely from the contributions of the players. He's active in Chat and listens to our complaints. He also isn't afraid to get goofy when us weirdo internetizens get weird. Great game and I can see myself sticking with it for a long time to come!
Interesting game - never played one like it. i'm an old guy been gaming for 3 or so yrs now, mostly no man's sky, minecraft, a couple others, recently started icarus and like it. This one isn't like anything i've played, and not really sure i know how to play it. mostly mining and salvaging for my needs and fabricating, mostly, it seems to level up. combat is kind of just watching it work, and seems to depend mostly on what level of weapon and armor you can get. Excavating is something that is really slow - not sure the goal. Accessed Nexus but looks like it's co-op and i prefer solo player, though never tried co-op/multi, but no interest in that. I've played about Lost Vessel about 2 weeks and will quit soon. Would like to kick in some support but wouldn't donate to an unknown - sorry guy who runs it. It's a helluva job you do - sometimes seems like the updates come hourly. Nice the bonuses you give out when you glitch something. Did voidshine suddenly lose it's strength - only got 3 hrs of IDLE last dose? Thanks for the interesting time.
I really enjoy this genre of games overall, this one is one of the best, and it's FREE. It's new and still growing, but the dev is active every day and talks in-game frequently, and the updates are fairly non-intrusive. A great game to just chill out to.
[h1]飞船坠了人还活着♥[/h1] 坠机在外星球,醒来身边就一个机器人,然后开始捡垃圾、造装备、升级、推图。五条技能线,近战远程虚空三种打法,装备分品级还有耐久度,打久了武器会坏得换。离线也能涨进度,关掉游戏角色还在自己刷,回来收菜就行。 能组队打远征和世界boss,也有阵营PVP,但都是可选的,不想跟人打就纯单机挂机也没问题。机器人助手全程跟着,算是个简易版的引导加陪伴。整体节奏很慢,不是那种推着你赶进度的设计,更像是每天上来收一波、调调build、看看数值涨了没有。 挂机RPG的底子,套了层科幻皮,但皮套得还算整齐,没有那种满屏充值入口的油腻感。 we need chinese!!!

stupid strange balancing of progression
This game is unplayable. It launches and I get stuck on the screen where it describes this is a single developer game. I can't click anythign on the page and i'm still allowed to click the icons on my desktop through the game. I do not recommend wasting any time with this.
this game scratches alot of itches for an idle game.
