Lost Vessel

Lost Vessel is a sci-fi idle RPG about surviving on a hostile alien world after crash-landing. You salvage the wreck, gather resources, craft equipment and fight your way toward returning to the stars. Progress continues while you are away, and you can play in bursts of thirty seconds or for sessions of five hours.

Skills and crafting

Five skills support one another: salvaging wreckage, mining the planet, harvesting alien flora, fabricating weapons and armor, and analyzing samples to unlock the next tiers. Endgame materials require components from all five skills.

Equipment progresses from common through rare and epic to legendary, with higher tiers available at the Forge. Legendary gear can grant effects such as a 5% chance to instantly kill, auras that increase skill speed by 25%, or damage reflection. You can switch between a combat loadout, a gathering loadout and a backup with one tap. Weapons wear down with use and break permanently if you let their durability run out, so repairs and equipment choices matter.

Combat and progression

Combat uses melee, ranged and void magic, with each enemy having a weakness. You can use critical hits, armor piercing, dodges and reflects, as well as instant kills from legendary gear. Zones grow more difficult as you advance, leading to a dimensional rift at the endgame.

Skills continue working while the browser or Steam client is closed. A 17-track mastery system gives permanent passive bonuses at milestones, while ship augments form a 110-level talent tree for tuning your build. There are no energy timers, stamina bars or premium currency.

I.D.L.E. and co-op

You can assemble I.D.L.E. from parts to run a second skill queue in parallel. He runs on Voidshine, an endgame fuel that requires materials from combat, biology and fabrication, and continues working while you sleep.

The Nexus Drift hub offers expeditions for 2–4 players, a world boss shared across the server, and specialist jobs that award weekly tokens. The optional Raiders PvP mode lets you choose a faction, raid other players, defend your colony and fight for territory; solo players do not lose anything by skipping these modes.

Supporter cosmetics

Optional cosmetic supporter packs add exclusive titles, name effects and profile flair. They provide no power or gameplay advantage.
