The code is: D4W14
It’s a Genji 1v1 with infinite blade, 10% cooldown on deflect and self heal after a kill with shurikens disabled.
It surpassed my expectation as it basically turned into a very fun sword fight between two Genjis. Deflect acts as block as it blocks blade but it doesn’t block swift strike, when your Deflect wears off there’s a very brief window that the other Genji can slash you before the deflect comes back online again, creating some highly intense scenario that tests a player’s reflex and mechanical skill.
Try it with a friend, I can almost guarantee you that you’ll like it.
