ok for the psp version..how do you aim up on the speaker???? i cant figure it out...

That is what i am stuck at too! figured it out for the first 2 speakers. in the first room, run to the PC and climb up, this should give the hieght you need to shoot the speaker. Smash the window to your left then go out the door to your right. Go accross the hallway and open the morgue. Run into the morgue and kill the goon to your right. After he is dead, climb on top of the gurney to your left. Again the right height to shoot the speaker. Jump down, turn left and shoot the other goon in the morgue, collect their ammo, go towards the double doors, run left and down the corridor, shoot the gun next to the stairs. This is where i am stuck! i cant figure out how to shoot the 3rd speaker, please help
