Anyone remember the Combine Mecha save?

Anyone remember playing around with this badass? I played around on this guy for hours on hours.

Since it was a save-file on a map from older versions, I can’t get it to work. Anyone got a dupe or got any tips for me to get it to work again?

couldnt find a dupe, but i found this
