Push a button for executions and you can revive "downed" teammates (before they get executed). No noticeable difference when you swing and hit, swing and miss, and swing and are blocked (so your best defense is a good offense when there's no difference between these 3 scenarios). It's just a shit game, made for spergy 12 year olds (like most populist games these days, they cater to the lowest common denominators).
