Deja Vu All Over Again
Head towards Carmelita for a scene. Once in control, you'll have to control Rioichi to retrieve his cane. Use Dragon Leap on top of the warning lights to reach it. Next, defeat the rat troopers that will storm in.
You'll be in the next room where you'll have to retrieve Bob's cane next. You'll still be using Rioichi to get it. Before proceeding, you can find a mask in this room. Jump over the gap to the right to find this mask behind the crates.
Use Dragon Leaps while timing your jumps to avoid getting hit by the stream of freezing gas. After getting the cane, Rioichi will go back to his time. You'll now use Bob to get Salim's cane. Make your way to the cane's location while avoiding the ice jets.
After getting Salim's cane, Bob will return to his time. Defeat the next wave of rat troopers to continue to the next room. Time your ascend on the blue chains to avoid getting hit by the toxic/freezing steam. Continue forth to retrieve Galleth's cane. Salim will now return to his time. It's Galleth's turn this time. Have him grab on the moving rings and destroy the blue canisters overhead to disable the floor traps. Make your way to Kid's cane and Sir Galleth will bid farewell.
Like before, take out the rat trooper reinforcements and proceed to the next room. Have Kid circle around the crate to the right and shoot the switch. Take note that this switch has an invisible timer; the hatch doors on the next corner will open after a short while. When that happens, shoot the switch again. Move forth and climb the pole. Jump down the pole first then turn around to find the mask on the platform across.
After getting the mask, climb up the pole again and swing to the nect platform. Now you have to stop the rotating blocks by shooting the switch again. Get across this as fast as possible. Do the same for the last set of blocks to reach a vault door. You have to shoot the correct patterns using Kid's crackshot.
After the scene, you'll be in a showdown with Le Paradox himself. This is a pretty easy and simple boss battle. You just have to carefully move from arm to arm to catch up with Le Paradox. Just press the correct button prompts that appear in the screen.
In the last part of the battle, you'll be sliding down the burning blimp. Face off with Le Paradox until he's defeated.
