Tip: Move Faster
Using the knife or handguns allow you to run faster, this comes in very handy when rushing to a sniper spot or ambush point before the enemy can get there. Also when throwing grenades or flashes if you hold down fire trigger then jump and release, your nades will go further, also using bankshots off of walls places flashes out of your eyesight easier. On Italy you can "teleport" in various spots on map. Using a partner in the wine cellar get on to highest crate, and have partner crouch on lower crate, jump on his head and both start jumping repeatedly and you can go through the ceiling and you appear at terrorist spawn point that is directly above that position. There are at least 4 different places in that map that it can be done.
Militia Glitch
Glitch: Militia Glitch
on the level militia, go to the very first sewer hole on the terrorist side, there should be a part you can climb up by jumping, get to the very top part and go to the front of the rock, face down a little bit not completely and walk backwards towards the little gap until you slide down now look up and move to the side, you should be inside the wall where noone can see/shoot you but you can shoot them, it may take a few tries to do i found it by accident and did it a few more times afterwards, just make sure noone catches you and reports you for cheating, it works on both single and multi player.
Glitch: The Bomb
Glitch: The Bomb
There is a glitch with the bomb. For example, on Dust2 if you go to bomb site A, have the person with the bomb climb along the side (the ramp type side) then walk along the slightly raised wall. Have a friend do the same before you but squat down on the box on the ramp type side close to the wall. Now jump onto the raised wall and get as close to the edge of the wall as you can, you may be partially on your friends head. Plant the bomb and it should be on his head. Now slowly have your friend back away and the bomb will fall right through the box. The CT's will be unable to find or defuse the bomb. Pretty fun trick just watch your back. I'm pretty sure this would work anywhere that there are boxes that you can get on top of near a bomb site.
