The CD case was all warped due to heat, the CD didn't survive either :/
How long was it there? Some years, i think
I played Mercenaries a bunch and had a blast loading up as many machine guns as I could on a relatively agile mech and just fully unloading on some big ass Atlas' cockpit in order to salvage it.
It wasn't exactly a fantastic strategy, but a great way to get a beast of a mech.
