Sentry droid,

Thanks for stopping by!

The last humans alive are being held captive by the machines in this prison fortress. Do you remember your creator? The reason that we're here?

It's time to go rogue and put an end to this madness. The humans can help you escape, but getting to them will not be easy.

Don't lose hope - The world we envisioned as children is still within reach!

I'll be in the walls.

Follow the breadcrumbs.
