Lost Vessel
A downloadable game
Welcome to Lost Vessel
Hey! I'm Simon, a solo dev and Lost Vessel is my very first game. A passion project I've been building from scratch. No team, no studio, just me and a vision. And now, I need your help to make it something great.
What is Lost Vessel?
Lost Vessel is a browser-based sci-fi idle RPG. You crash-land on a hostile alien planet as the sole survivor of a lost vessel. From nothing, you salvage, mine, craft, research, and fight your way from crash survivor to interstellar civilization - all in your browser, no download needed (but actually soon available if you fancy one). It combines classic Browsergame, new reward dynamics and - in the future - [REDACTED].

Install instructions
You can just fire up the .exe and an Installer will guide you through the process.
Since I did not buy a code signing certificate yet, so you might have to click "More info" and "Run anyway". If you have questions join the discord, you find the link ingame on the left side. Thanks for playing and looking forward to your feedback.
