Narnia Prince Caspian

nothing wrong with the other solutions but i chose the

Grappling hook mission

on the ruins of caer carnival(2nd window/level on menu screen) you start on beach just go left and you will see a pile of rocks..select one of the lad's to move the rock's then enter for mission to start

due to the fact all you do is run through a small cave tunnel which has gust's of wind at certain points blowing across it...you have a torch which you use to light a few fire's to keep the bats off you (they attack if torch get's put out) there is two places where you must knock over a pillar to block a section of wind off...press b then spam a

also there are two missing levers..one is under/by a couple of barrels behind you on right(when looking at lever)..the other is up some stairs under/in front of some more rocks...


you will reach the end of the tunnel after lighting some vines on a arch..you must walk through the wind your torch will go out but you are protected by the burning vines/arch..make sure when across you relight your torch from the burning vines on your right you will then find a chest.. open it by pressing b then spamming a..you will get your mission item with a cut scene..

then you are back on the beach...so just rinse & repeat..on the next run through it is even quicker due to the fact you won't be opening any chests....and missing out 1 lever

i used 2 controllers on my own.. with a friend helping you would fly through this....

this achievement glitched for me & i know some other people have had the same problem.
i started a new game & replayed the level 'protect the battlements'. i played it 15 times til it unlocked. took me about 25 minutes.
it's practically impossible to die in this area. however, only go to this area if you actually have someone playing co-op with you. i know some people have done the achievement on their own but i wouldnt advise it on this level because teamwork is needed at the beginning.
the second player doesn't have to be brilliant at playing the game either because the level is so easy. incredibly boring though.

I completed this achievement easily without friends; just plug in a second controller.

Choose the "Protect the Battlements" mission. This is the mission located through the tower at the top of the stairway you had cleared of debris. I found I could complete a mission in just a few minutes.

At the beginning, I completely ignored the second controller; toward the end of my run for 15 coop missions, I was able to use the minotaur to toss two barrels and free a giant. If you take much more time than that, you'll need to start running around and helping keep Telmarine's off your defenseless "partner" and need to move your partner's character around so you can find additional barrels and crates to hurl. Just focus on killing the Telmarines tethering one of the giant's sides ... once the giant has one side clear, he will clear the other and the cutscene advances the play to the battlefield.

Play the battlefield portion of this level through as in single player but have the second controller nearby and push the other giant (your partner) forward with you. By moving forward slowly, you can clear the area of archers and not allowing any to escape. Escaped archers mean you'll have to look around the battlefield for them. When they escape the first area (the one to the right), they tend to run to the left; those on the left will either run farther left, will try to head back to the right, or will move toward the battlement/balcony. This unknown means you have to do a bit of searching.

The only problems encountered by not having a second player on this level are that your partner may start to get tethered down (if you only have one or two tetherers, you can continue walking almost nornally ... more than that slowy you down); or you have to continue to manage the second controller when searching around the board for the Telmarine archers who have escaped your giant. Controlling two characters with separate controllers can be annoying.

This level is good because you stand almost zero chance of being killed AND it's fast.
