JAK2 RENEGADE WALKTHROUGH: BLOWING UP AMMO AT FORTRESS Go through the 2 rods. The tank should start shooting at you. Keep on going through until you reach a room with platforms spinning. In the middle of the structure supporting these platforms, there should be a blue cylinder with electricity inside it. Smash them. There are 2. The easiest way to smash them is to jump on them and press O. Once you smash both of them, a 'mini video' should come up of 2 rods with electricity flowing between them, turning into 2 rods with no electricity going between them. Go through. You should be able to work your way through now.
