Two lines in the official description change how you end a session: buildings autosave, and your base fights offline. Public notes do not say how many waves run while you are gone, which pieces shoot without a player, or whether a manual repair button exists. Plan for the sentence that is published: the base you leave is the base that keeps fighting.
Logout walk
Do this before you leave place 139536504610209.
- Look around the whole footprint, not just the entrance you like.
- Stand on the monster approach. Ask whether anything still hits that lane if the first piece is gone.
- Close side gaps that only worked because you were standing there.
- Delete test pieces. Autosave keeps them, and a stray opening becomes a path.
- Do not spend the last resource on a new wing you have not sealed.
- If friends are still in the server, say you are leaving and who may still edit. A last-second delete can undo the walk.
Then leave through the normal Roblox exit when you can. The save timing itself is not published, so a force-quit in the middle of a placement is a bad habit even though the exact penalty is unknown.
What to build if you expect to log out
- One sealed approach beats several open gates you planned to watch yourself.
- Two modest pieces on the same lane beat one piece that the whole base depends on.
- An inner line gives the offline fight something after the outer line fails.
- A base that only lives because you repair every few seconds is not an offline base yet. Stabilize live waves first, using Survive waves.
Early sessions should not skip live clears to chase an unattended setup. The offline fight uses the holes you already have.
After you come back
Look at what actually broke. Reinforce that face. Do not assume the untouched sides are safe. If the whole lane collapsed, shrink the footprint and recover with the order in Bosses: core path, one covered lane, then extras.
What this does not mean
Offline defense is not permission to run an injector, an auto-clicker, or a script that keeps a second client alive. Those tools are outside Roblox rules, and this site does not provide them. The official feature is the base fighting without you, not a third-party client.
Also confirm you audited this experience. A logout routine from Build Base to Survive VERITY, including its night timer and block names, is a different game. Identity checks are in Avoid the wrong Verity game.
