Trying to remember an old PS2 game (from a demo disc)

Hey guys so Ive been trying to find out the name of this super cool demo game I played a while ago on the ps2. This disc had this game and a bunch of other games I don't remember sadly.
Anyway, the game was super similar to Jackie Chan kind of games in that you can run on walls and parkour but if I remember correctly you could also use guns? In the demo you where on the streets and back alleys fighting your way to escape from what I remember. Any ideas? Apparently it wasn't an actual Jackie Chan game because the only PS2 Jackie Chan game is the Adventures animated game.
