If you played the first one you should play this one.
Gameplay: Yes it is repeptitive. I found myself just wanting to run away from the enemies because i didnt want to deal with them or i was looking for an upgrade. Does not slow down the gameplay too much however. New guns and moves are good, but my square button is getting mushy.
Sound: the sound track isnt that special, but does fit the mood of Death Jr. Not much sound glitches(if any at all). Solid!
Graphics: Amazing! one of the psp's best. Beautiful character models and enemies!
Value: This is a good amount of fun. Has a good amount of upgrades. Bosses can get upsetting at times, but hey thats the game.
Tilt: There is replay value to go back and play as a different character or if you missed an upgrade or if you wanted to unlock a new move. I would keep playing it for fun after that i just hope my psp can hold up with the button mashing.
All and all a decent game!
