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.

Je trouve l'ambiance du jeu relaxante. Tu récoltes des matériaux, tu t'améliores personnellement de diverses manières et tu participes aussi à des objectifs communautaires. La communauté est sympa. Le pvp existe, mais n'est pas envahissant et ne viendra pas impacter ta partie solo. (c'est plus un à coté) Pas d'avantages premium, tout le monde est sur un pied d'égalité vis à vis de son temps de jeu. J'attend de voir ce que le jeu nous réserve pour l'avenir, mais pour l'instant j'aime bien.

dont play it long term! you need to much ♥♥♥♥ for upgrades that dont do ♥♥♥♥ weapons have durability of paper and cost to much to make to be word it you have an idle companion but cant use it until late game and it burn items you cant make for them to be burn items. for upgrades you only get a +3 MAX to the items you get and the speed ad witch you get them makes that not worth it. can yoiu increase the speed ad witch you get thing yes but it is per catecory and you spend to much on it min 300.000 to get to level 4 out of 5 and thats the basic one the other one also hase 5 levels but you need advanced stuf to upgrade witch comes out rufly the same but in defrend items you log in look ad what you still need and then reset the idle timer so every 8 hours you can reset if you can do that?

Fun idle game. Cool mechanics, looks nice, dev very active. Played for hundreds of hours in browser which works as good as via steam. Cool if you dont want to download anything. Would recommend to check it out.
Exactly what I was looking for in an Idle style game.
