Always Bank on Chase is the penultimate mission in LEGO City Undercover: The Chase Begins.
Walkthrough[]
A bank has been robbed, so jump in a car and drive there immediately. Starting this mission grants Chase a new ability when he is in his Fireman costume, the ability to use the Axe on doors. Do it on the door that is shown in the scene to get parts to a lever. Throw the lever together and then pull it.
Use the grappling hook to reach the roof. Switch to the Astronaut costume and then use the Jetpack. You'll land in front of a door that needs smashed down with the Axe. Do this and use the pieces inside to create another grapple point. Use this grapple point to go up another level on the bank.
A multitude of enemies will rush out to meet Chase. Take them all down with Chase's expert fighting skills. A panel below will open up. Go there now and then switch to the Construction Worker costume because inside that alcove is some concrete that needs smashing. Smash through it and drop through the hole to be in the bank proper.
Fight the enemies that come out. Then smash everything. You can use the pieces to start putting together a water cannon as Rex Fury is blocking your path to him and the vault with some fire. Push the lion statue over a bit and then switch to the Fireman costume. Smash the barricade to free the people and then go inside there to find a water cooler.
Break the water cooler and then pick up the gallon of water and take it to the cannon. Use it to spray down the fire. Rex will start another fire and even destroy your cannon. More enemies will come out to support him, so defeat those enemies and then push the lion statue on the other side of the room. Smash the barricade, free the hostages, go inside, get the water cooler. Use the pieces to the new water cannon to build it and then place the water cooler container on it to equip it with water.
Rex will retreat inside the vault and a red laser barricade will pop up to block your progress. You can create a Color Swapper with the parts of the old water cannon. Take the red color and shoot the green button above the two doors with it. Then use your Robber costume to break into both of the doors.
Inside the door to the left of the vault you will find parts to create a wall to climb. The second door will have parts to a lever. Create both and then pull the lever to make the hand grips position themselves in such a way that you are able to reach the control panel above. Use it to remove the red lasers that are protecting Rex.
Rex will escape and now you have to smash into his truck repeatedly to drain it of its hearts. When enough damage is done, Rex will try to escape on foot, and will then jump onto a speeding truck, though Chase will manage to get on it as well. You will have to fight enemies that jump on the truck and then try to pull away the shield Rex has.
A firetruck commandeered by Rex's man will drive by and start spraying at Chase with water. Jump over the water and ignore Rex for now. Jump over to the adjacent truck and use the Simon Says Astronaut thing. Hilariously, this will summon a UFO to abduct the goon on the firetruck.
Now return to the blue truck with Rex. Use the grappling hook to yank Rex's shield away from him. Then it's just a matter of throwing Rex off of the roof to defeat him.[1]
