Yeah. The least they could have done is put Neo in Multiplayer, and each win would unlock another opponent:
1) Neo vs Morpheus (in that place where the fight was held in the first Matrix movie).
2) Neo vs the 3 agents he versed in the first Matrix (M1).
3) Neo vs vampires from the Merovingian place.
4) Neo vs Merovingian.
4) Neo vs thousands of Smiths (like in Reloaded [M2]).
And I won't go to Revolutions since the game came out before M3.
