Spider-Man 3

This is so old it's unlikely anyone will see this but I'm giving it a shot. Do you need to complete EVERY side mission for this or just the story? The reason I ask is my friend played this on my tag years ago and did a lot of the side mission achievements, he got the Eddie Brock achievement for beating Venom but this achievement is still locked. I was thinking about going back to this a finishing it up because it's the only SM game I haven't played, but I don't want to re-do everything he did if I don't have to.

It's been 5 years since I've played the game (as you can see), but I believe when I said 'every storyline', it probably meant EVERY storyline mission, so Dewolfe, Connors, Daily Bugle, and possible the Mary Jane thrill rides. It doesn't appear that Bank Robbery missions, Crime Spree missions, Petty Theft, or random city missions count since I got all of those after this. Hope it helps, but like I said it's been many years since I've touched the game so I'm not sure of everything. :P
