Not my screenshot btw but I hunted it down after playing through this part. I've been playing it for a bit now (I'm on path C) and it's still not 100% obvious to me that it's an explicitly pro-leftist, though there are some hints. For example, there are also 2 robots named Marx and Engels, where Marx dies early and you talk to Engels as a side quest. I'd love to hear what your thoughts are on this game if you've played it before.
I've considered playing this a dozen times, but its a sequel, which is also a spinoff. Do I need to know anything for this one?
