So I'm at the end of the game (right in front of the point of no return to be exact) and I have about 52 tonics. I have spent all of my ADAM on upgrades and such, but there are still tonics I can buy. I also wouldn't be supprised fi I missed a tonic somewhere. Have I locked myself out of this trophy, or will I gain more ADAM before the end of the game so I can buy the rest of these tonics. Oh I have also been SAVING the Little Sisters.
