Lost Vessel pairs idle progression with meaningful combat encounters on a hostile alien planet. You develop five core skills while engaging in melee, ranged, and void magic battles against procedural threats and a persistent world boss that challenges entire factions. The game rewards both active play and offline grinding, supporting solo exploration or cooperative raids without requiring purchases for competitive advantage.
About this game
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. No pay-to-win.

Lost Vessel is an incremental game. There are many in the field, so what sets this one apart? Well...
• It's free to play, and not pay-to-win (purchases are cosmetic.)
• The dev is active and regularly updates (sometimes with spamming frequency)
• It has a cute little bot mascot (who requires 'shine to keep fueled)
• There's still stuff to do after completing all the base game content (end/post-game material)
• It has an in-game chat (with active players)
The chat is the best part, imo. These kind of games can get mind numbing in short order, but having something to read while the idling to craft/collect resources makes a big difference.
Normally I'd check out of game like this in 2-3 days, but here I am a month later and still enjoying it. Maybe you will too!
I've played a lot on the web version, so my play time here isn't exactly accurate.
It's definitely one of the better idle games. Early on you need to micromanage what you do to craft items to help you progress, and later you'll be getting resources for permanent upgrades and to craft legendary items (1% chance). The fact resources are always useful (except analysis... although there is a use for it that's in beta) makes it quite fun, since you never really waste time as long as you're doing something.
The game is also completely free, which is honestly cool. There are supporter packs with some cosmetics (pretty much just for your profile and chat visuals) but they are there mainly to support the dev.
Hey guys, just a quick Steam App patch to address the Chromium / Electron wrap mishandling minimizing and idling on longer away-times. This has been an ongoing issue and this is just one part of the tech-side. Still fixing things on the server-side. If you are having issues, let me know in Discord and please report the specifics in the bug-channel - when you can. Thanks for playing!

The pitch on it says the thing plainly: the colony has surveyed outward since the day it landed, and nobody thought to survey down. 110 million points, half of what the Spire took, rising through four stages you can watch on the map: survey stakes, sounding rig, shaft head, first cut. Priced on the same ladder as the Spire, by tier and processing depth rather than by what anyone is sitting on. Shared items keep the value they already had, so nothing is worth more or less depending on which build you pour it into. What is at the bottom is the entire point of digging, and I am not telling you before you get there. The settlement map remembers Finished projects keep their plot. The Spire still stands where you built it, its final numbers frozen the day it completed: the total, the people who carried it, and what you put in yourself. You can move between them, monument to active build and back. Finishing one no longer quietly erases it to make room for the next. Fixes World boss hits reward your build again. Showcased items show visitors their real appearance, skins included. Short absences now report what happened while you were gone, and time you were present for is no longer simulated a second time. Roadmap no longer leaves a pane stranded over the window after you close it. Tutorial survives losing your first session. Names settle after the first few changes. Top bar dropdowns open above the interface, the bar wraps instead of running off the edge on narrow screens, and the floating tools size properly on phones. Yield popups stopped throwing on every drop.

The Resonance Spire - the first construction project. One build for the whole server: every Nexus survivor can contribute materials, everything feeds a single progress total, and the structure rises on the map in real time through its construction phases. Permanent contributions - every donation is recorded, and the top 10 contributors become part of the finished structure forever. Nobody knows what happens when it stands. The readings coming off that ground are strange. Find the site in the Nexus. Gifting Personal gifts - gift a Supporter Pack directly to a specific survivor from their profile. Steam support - the whole gifting system, personal gifts and Signal Boost both, now works on Steam through the Steam wallet, exactly like on web. Chat alerts - gifts announced in chat now show the actual supply crate being sent, with a glow matching its tier. Quality of Life Audio controls moved to a speaker button in the top bar, with the same controls in a cleaner popover. Forge odds - the legendary chance now updates live as a tier runs dry. Badge privacy - supporter and founder badges can be hidden in chat and on your profile, same as the Support Ladder badge. Fixes and Balance Distress Relay bounty crates now follow your research progression instead of reaching past it. Reawakening experience bonus now caps at plus 110 percent (eleven prestiges). Offline yield - legendary tool effects that add extra yield now apply fully to offline progress, including crafting. If your overnight returns looked thinner than your live sessions, that was why.
