How to unlock secret levels.
If you have any type of box to drop, plant a claymore they're first, then drop it ontop. If you die, the guy who tries to steal the box will get blown up. You'll both be even for kills, but at least yours was wicked. <img src="http://i.neoseeker.com/d/icons/wink.gif" border=0 vspace=2 alt="" />
On highrise go to the H with the helicopter on it. Look to the left, you will see a crane that right beside a building with a ladder. Go to that building and climb the ladder and look to the left you will see a floating platform. Jump on to the platform then walk over to the crane,once you areat the farthest point,press the a button. You with climb up on to the crane,this spot is great for snipers. You can walk anywere you like on the crane. There are many more places to go while you are on the crane such as if you look to the left, you will see platform jump on to it and there you are!
There is actually a way tobget on top of one of the buldings on Highrise.
When leaving the Attacker building on Highrise, head to the right side of the building. Once you get to the edge, you should immediately notice a platform hanging askew on the side of the building. You can actually jump on to the side railing of this platform and climb up it like a ladder. What you do is you must get on the edge of the building and run and jump to the side railing BUT YOU MUST IMMEDIATELY LET GO OF THE CONTROL STICK ONCE YOU HIT THE RAIL OR YOU WILL FALL.
Once you've got ahold of it, climb on up to the top. Now you should notice a ledge that runs along the length of the building. Follow this ledge to the other side where there will be another platform you can jump up on and from there get to the roof. You'll be extremely exposed while doing this so do it quickly and stealthily.
Once you've made it you will be rewarded with the greatest vantage point in the entire game. Enjoy!
