much better then the first one
in this game you get sucked in to a rift gate and you end up in haven city where there is war whit the metalheads(some cool monsters). the story of the game is really awesome and its full whit twists, the story really doesnt let you stop playing cause you wanna know the end. awesome.
the graphics are way better than the first one , it is really one of the best looking ps2 games top that whit great music and an all new great gameplay.
in this game you have guns through the game you'll get new guns and upgrades, you also have new powers wich let you turn into dark jak if you got enough dark eco, it isnt such a big deal but its cool .
this game is long and its really a challange, the lack of checkpoints really can make the game frustrating but thats ok.
this game is just amazing if your in the platform or action/adventure genre you got to have it ! its awesome .
