| Mr Khan said: I'm going to have to play that again, because i remember that from Sin and Punishment 1 (though i never got around to beating that one at all, but i got enough of the story to piece together what was really going on), but i didn't get that at all out of S&P2 I also really didn't get how vastly the earth changed between the two, if Isa was actualy Saki and Airen's kid, couldn't be more than 30 years later at absolute most, but earth went from something vaguely recognizable to us, to this place totally covered over with plates |
The final part that puts it all together is a brief cutscene that airs after the credits, once you beat Isa And Kachi mode.
As for the Earth part, there are multiple Earths. The one in this game has already been destroyed; you're just playing in its ruins, and you're pretty much the only humans on the planet. Isa, and the humans chasing him, come from a different Earth entirely, which in turn may or may not be a DIFFERENT Earth than the one in the first game.
Long story short, ignore the plot and just shoot stuff!
