now listen closely.
leaning is an art only the most powerful and skillful can master
The rest will suffer if they use this technique
I highly suggest that you read the guides before of how to walk, jump and crouch from the other masters.

Now for the technique
to lean one must HOLD q in order to lean to the left. This allows you to look from behind cover and shoot and kill your enemies.

The next technique is just as hard and just as rewarding.
To lean to the right one must HOLD e.
this will allow the user to do the same as leaning to the left
except now you lean to the right.

assuming you have survived you have now mastered the art of leaning
now go forth my warriors and tear into your enemies with your newfound powers!
