I too just beat the main storyline. This game is really, really intense. Not just gameplay wise, but storywise too. Very immersive. By the end I really got creeped out by what was going on. While I'm very confused by the story I'm also very intrigued by it. I think that's the main thing why this game is so awesome and really adds something to the setup of 1; the whole storyline is one big intertwining puzzle.
I'm trying to puzzle it together, please help if you feel like it!
(HEAVY SPOILERS):
The Pig Butcher is the criminal detective Parbo is after. The Pig Butcher is the actor, who gets killed by the actress.
The Russian mob Son's Henchman gets killed by the Fans after his lady leaves him with all his cash.
The Fans get killed by the Russian mob Son.
Jake the Snake was in the army, or am I wrong? And was Jacket in that crew too? And is the guy with the glasses and beard the guy from the convenience store in 1?
The Writer gets a hold of Richter (which indicates Jacket didn't kill him in 1), who is in Hawaii and wants a flight ticket for his mom.
Richter is the guy escaping from prison. While in prison, he gets a visit from the Janitors from 1, right? In the ending he is watching the news when the presidents get killed.
Jacket is in prison, right? And gets blown up by the nukes too.
I only just realised that in the final mission the Russian Mob Son actually kills the trippy versions of the fans and it is actually the same event as you have played through as the fans. The swan creature did ring a bell but I thought it would just be a bad trip out of memory. Pretty cool that it is the real deal.
Does the Russion Mob Son walk off the roof and fall to his death at the end? I don't know.
I can't wait to go through it again.
