How to Update ROS Legacy and Keep Your Progress
Install over the top, let your account do its job, and never lose a season to an uninstall again.

CONTENTS On this page
Updates in a live revival are routine, and losing progress to one should be impossible. It nearly is, provided you follow the one rule this guide exists to state. The current build is always the one on the ROS Legacy download page, with its version in the homepage details table.
The over-the-top rule
Download the new file and install it directly over your existing copy. Never uninstall first. Your progress, settings and identity belong to your Mirae Labs account, and the over-the-top install keeps the app's local side intact as well, so an update costs two minutes and changes nothing you own.
After the update
Sign in if asked, glance at your settings (updates occasionally tidy menus), and check whether anything new wants downloading, like map data. Then play a casual match before a ranked one, the same advice as after any change to your setup.
The before-you-update checklist
Sixty seconds of preparation makes updates boring, which is what you want. Confirm you know the email on your Mirae Labs account, because that login is your progress. Check free storage beyond the file size, since an install that runs out of room mid-write is the one genuinely messy failure. Update on Wi-Fi, and update between sessions rather than with a squad waiting in a lobby. Every refresh starts in the same place: the ROS Legacy download page holds the current verified file. Then install over the existing copy and let the game pick up exactly where it left off, account, settings and all.
When updates go wrong
Almost always, a failed update is a partial download wearing a disguise. Check the file size against the table, fetch the file again on a steadier connection, and install it over the top once more. Your account makes even a full reinstall survivable, which is exactly what it is for. Update over the top and ROS Legacy keeps everything you earned.
If an update goes wrong
Stay calm and diagnose in order. A failed install is usually storage or a partial download: free space, fetch the file again cleanly, install over the top. A sign-in hiccup after updating is usually a password saved wrong, not progress lost, because progress lives with the account online. Never uninstall in a panic; uninstalling is the one step that cannot help and occasionally hurts. our ROS Legacy installation walkthrough lays out the full install sequence if you ever do start from zero, and the ROS Legacy troubleshooting guide keeps every reader-reported update problem and its fix in one honest list.
Current is a habit, not an event
Players who update as routine maintenance never meet the update problems in this guide; their games simply stay current, season after season. Build the habit: check the table, fetch the file, install over the top, play. Two minutes, a few times a year, in exchange for never fighting your own install. In a live game the present build is where the lobbies, events and fixes all live, and ROS Legacy rewards the players who live there with it. Keep ROS Legacy current and it will keep its side of the bargain.
Quick Answers
Will updating delete my progress?
No. Progress belongs to your account, and installing over the top preserves the local side too.
How do I know I am behind?
Compare the version in the homepage details table with the build shown in your game.
Should I update mid-season?
Yes. Live games assume the current build for events, modes and matchmaking.
