This reports details the technique used to reach the top of the tower in the Siberia map. This is achieved through a bug in the game, and is not permitted during normal play. It is shown not so you may (try to) use it to your advantage, but so you are aware of how it may be used against you.

At the "front" of the building the tower is on top on there is a big garage-like door(stand by the small guard tower and look towards the building, then walk straight forward). Go up to the door and crouch down on one of the sides. Press space to begin climbing up the small thingy on the side(sorry, my English is bad today. Got a bit too little sleep lately..), and then press C in the middle of the climb.

You'll go back to a crouched position and begin floating backwards very slowly. Position yourself looking away from the building and wait for until you float into the wall. You'll start falling downwards, below the building. Wait a few seconds(6-8) then press C. You'll start climbing. Press C again *before* the climb bar reaches maximum. You'll start falling down again, but keep pressing C(but press again before the bar reaches max) and you'll slowly start climbing up to the top of the tower.

This works on every map where you can climb something. Just crouch, climb and crouch again in the middle of the climb and you'll start floating backwards. Then you can use the C key to "climb" anywhere you want.

By posting this I take quite a risk(everybody could start cheating..), but taken into account that this bug takes an incredible amount of time to pull off successfully, I assume not too many people will use it. The chance of successfully gaining an advantage from the manoeuvre is very slim. Besides, it's pretty easy to catch cheaters. If anyone keep climbing and/or crouching by the big door on Siberia I, they're probably trying to cheat. Then you can cap'em and boot'em ;)

"Cheat" can be defined as "To violate rules deliberately, as in a game", and therefore the use of this technique can legitimately be classed as cheating. However to "cheat" in a game is to "seek an advantage by unfair means", and to suggest there is an advantage in leaving yourself open for the 2 minutes is takes to complete this move would be foolish.
