i could do a wall jump, but no matter how many times i try, i could never get the wall climb right. i also have trouble super jumping sometimes (could binding jump and duck to one key work?).
backflip is an awesome way to finish off ur opponents, but u need extremely light gear to perform. also try to do the running jump, then press duck+kick works well. i found no use for that new bullet dodge stunt (like the one neo does in matrix 1 when he was dodging the agent's bullets) since you can just shoot at his legs to kill him.
only problem is that backflipping and other moves is making me dizzy
try 3rd person mode. its actually very cheap, since u can see around corners and behind pillars that you couldnt in 1st person. i often like to hide behind pillars (i usually carry only combat knives and a glock 18) and when they pass by, i do a flying kick to disarm him, then throw a knife at them while theyre trying to figure out what going on.
