Which are the "necessary" trophies I need to get to get the final Platinum trophy for BIOSHOCK 2?

Hi Gamers:

I just got all the platinum trophy for Bioschok 1 for the PS3, I'm so glad because my second to last one was the damn Tonic collector trophy, which I missed on my second run and I had to play the game for a third ( which I don't really mind since Bioshock is a excellent game) to get it. Now I just started playing Bioshock 2, and my question to you gamers is: If you can provide me with a list of all the "necessary" trophies I need to get the final Platinum trophy for Bioshock 2? I ask this because I don't know if I have to get the trophies on the "Multiplayer" mode as well? If so, please tell me. I don't want to get any unnecessary trophies that don't count towards the platinum. I don't want to BUY any Bioshock 2 downloads, so I don't know if I have to buy the additional downloads to get the Platinum. Another question, is there a trophy in Bioshock 2 that is similar or the same as the damn "Tonic Collector trophy in Bioshock 1? If so, which one is it? So that I can focus on that one first before I miss it. LOL. Again please lists all the necessary trophies to get the Platinum Trophy for Bioshock 2. I've checked many websites but they don't say which ones are the necessary ones for the the Platinum. Thank you so much in advance for your answers.

Sincerely,

Junior.

P.S. I started playing Bioshock 2 on the hard difficulty setting, since I like to think of myself as an expert in Bioshock 1. However, the controls for the sequel feel strange. I guess I'm not used to the game controls yet. Lol.
