Very much like you build or fix a computer or any kind of electronic device really, you gotta tear it open and see what leaks and see what is broken underneath.
Evaluate then fix it, and put it all back together and then ship it back once it's done.
Fun game. It's not too long either i reckon. Has some funny bits and quite some challenging missions, which
i'm sure you'll be able to overcome. :)
The game runs on very low specs, but it's not ideal. I'd recommend a somewhat decent GPU so the game isn't slow or have stutters.
