The time has come (well, it has returned at least) for you to grab some friends, a random champion and hop into a no cooldown, no mana, full damage, League of Legends apocalypse. All Random Ultra Rapid Fire has returned and everyone is stoked about it.
Just one of the many rotating game modes, AR URF is back for a full two weeks, so you have plenty of time to get your Lux-laser-spam-fix. The event will run from August 11 to August 24. While this sadly means that we will have to wait another few months before we get to play Ornn in URF, you and your friends will be able to play with no cooldowns until your eyes literally bleed (I assume that two weeks is long enough for that).
The re-release of AR URF could not come soon enough after the pretty constant feeling nature of Poro King after Poro King broken up only by Ascension. The only real question I have now is: where the hell is Black Market Brawlers? Give me back my horrible pirate game mode!
