I kinda liked the style of endings, with the audio over the end credits, and the swat team breaking in. One ending was shocking in that the NY bomb explodes and kills millions, and sam is implicated! I also got the true ending where you take out both bombs with sam on the run...isnt there another one? how do you get it? and is there any way for erica to become sams love interest? Im sure I read it was possible...
And does lambert die, or what? He doesn't seem to, just be hurt....
but in the PSP version of splinter cell, essentials, he does die...and its treated like that in the storyline too.
Speaking of the psp game, it seems, in terms of plot anyway, to be a semi sequel to double agent, with lambert dead, fisher on the run and trying to contact old friends at the nsa, and the new director, williams, seeming VERY dodgy. It seems to imply the next, X BOX 360 EXCLUSIVE

D) chapter will deal with sam trying to get his life back and exposing williams. Very interesting directions.
