Overwatch McCree Guide and Tips
From a relatively distant range you should start a fight by rattling off your basic left-click attack. Save your rapid right-mouse button attack for when the enemy is much closer - they'll be easier to finish off as they are more likely to take a rapid succession of bullets to the face.

§ To increase your odds of pulling off this move, consider throwing your Flashbang right at them. This will stun them, giving you a window of opportunity to fan off your Peacekeeper bullets, then Combat Roll to top up your bullets once again. From here you should be able to pick off the final slivers of their health, but you need to be extremely quick at every stage of this process to pull this off.
§ Given his lack of escape abilities, McCree is often best played close by to a tank or support Hero that he can guard against flanking attacks.
§ Keep in mind that - while extremely effective at temporarily disabling an enemy Hero - McCree's Flashbang does not have a great deal of range. Practise makes perfect here, so don't be too discourage if at first you're not nailing this perfectly each time.
§ Unlike characters such as Lucio, who's weapon has a certain weight behind it, McCree owns a so-called hit-scan weapon. This means there is no travel time to take into account with your aiming, and so anything you target and fire at gets hit - full stop.
