Ratchet & Clank: Up Your Arsenal/Marcadia

Get to the Palace
At the autovendor next to your ship, the Spitting Hydra is now available. You will have two allies helping shoot the enemies for a little while. Follow the path and clear out the first large area with the broken railings. The pots in this area are breakable for extra bolts. Follow the stairs up, and get the jackpot crate which will double all bolts and experience that you obtain. Clear out all the enemies in the area and follow the stairs up until your timer runs out. Go back to the large room you were in, and use a boost jump to get up to the small northern platform. There is a tower of crates with an exploding crate at the bottom. Shoot the exploding crate and get all the bolts from these crates. From here you can also use the N60 Storm to pick off some of the enemies ahead.

Follow the stairs up past the small pool of water and you will enter an area with multiple enemies and a large mechanical enemy in the centre. Take out all the smaller enemies with the Shock Blaster or N60 Storm, and then switch to the Nitro Launcher to take out the larger enemy. There is also another large enemy across the bridge, so use the Nitro Launcher to take him out as well. Stretch Jump across the gap.

On the other side, there is an Inferno Power crate. Destroy that crate and take out all the enemies with your Omniwrench. Once you kill the last enemy, go back and break all the crates for bolts and ammo before descending the stairs. A short cutscene will follow, and then you must help the ranger clear out multiple enemies on the path to the dropship. Break all the remaining crates and then climb aboard the dropship.

Operation: IRON SHIELD
You now begin a series of Battle Missions. You will receive a prize after each.

Secure the Area

 * Drive the Tyhrranoids out of the compound then defend the area against a series of brutal attacks.

Use the N60 Storm to take out the enemies that are already there when you arrive, and the Nitro Launcher to take out the larger enemies armed with lasers. Multiple groups of enemies will soon begin to attack. Use the Nitro launcher on the larger enemies and alternate between the Shock Blaster and N60 Storm for the weaker enemies. The minimap at the bottom right corner of your screen will show you where the enemies are arriving.
 * Prize: 3000 Bolts

Air Assault

 * ''The Rangers can't hold out much longer. They need backup, now!  Save as many Rangers as you can.

There are 4 Rangers in the centre of the map who you must protect. As long as at least one of the Rangers survives, you will complete the mission.
 * Prize: 4500 Bolts

Turret Command

 * Get to the plasma turret and blast those 'noid dropships out of the sky!

You will control a turret and you have to destroy the dropships. You have unlimited ammo, so hold down the button and continue to shoot the enemies. You will have to lead your shots by aiming ahead of the dropships, since the bullets take some time to travel.
 * Prize: 6000 Bolts

Under the Gun

 * Provide covering fire for the repair crew until they can get the turret operational again.

You have to make sure at least one member of the repair crew survives. It will take them 2:00 minutes to repair the turret, so stay close to them and attack any enemies that come nearby.
 * Prize: 7500 Bolts

Hit n' Run

 * Use the bolt cranks to activate the automated turrets in sequence.

You need to activate the turrets in the proper order. The next turret you must activate will be highlighted as a green dot on your minimap. Use to activate the bolts on the small platforms with your Omnihammer. The turrets will be able to attack the dropships in the air, but once they release their units, you must destroy any land based enemies.
 * Prize: 9000 Bolts
