Can't keep your co-op ICARUS prospect going when the host is offline? We built a fix
Hey r/Icarus,
My friend and I built SaveSync, a tool that syncs co-op save files between players so you and your friends can keep the same ICARUS prospect going without renting a dedicated server or passing save files around by hand.
The problem we kept hitting: a co-op save lives on whoever is hosting. Your prospect, your base, your character progression and gear, all locked to one machine. When the host is offline, the run is offline. A dedicated server works but it's setup and a monthly cost for what's usually just a few friends.
We hit this wall ourselves playing Schedule 1 together. One of us was sick at home, the other stuck at work, and the save was locked on the host's machine. So we built SaveSync, first just for ourselves. Turns out it's a problem across a ton of co-op games, ICARUS included.
How it works: SaveSync auto syncs your save to the cloud after each session. When your friend wants to play, they pull the latest save and host it themselves on their own machine. No dedicated server, no monthly fees, no manual file swapping, and you keep a full timestamped history so a bad drop can be rolled back.

What players have said:
"We have enjoyed the ease and convenience of a server with the security of local world hosting. Also allowing those in a closer geological location to have lower ping." - Steam review, 459 hours played
"Great product, works amazingly well and does exactly what it promises. Not having to rent or manage a private server is a huge plus especially if you just want to jump in and play without extra hassle or costs." - Steam review, 1,122 hours played
