Is this the version that has the extra bonus weapon? Plus the making of commentary? Other bonus stuff?

I'd also like to know what this version of the game includes.

Edit:
Its not the directors cut, no bonus stuff :(

Sigh, that's too bad... Not worth buy for me unfortunately... I liked the bonus weapon when I played the game back in the day, and the historical facts that popped up.

Does anyone remember what the exclusive weapon was, its been so long since I played the game?

It's the use it in the normal edition through the developer console.

I have the DVD for the collector's edition. It's not that hard to get the game to work.
