Showdown was and still is the only true 1v1 or 2v2 game mode. This game mode takes place on the Howling Abyss and randomly matches you with another player. The neat thing about this mode is that there is more than one way to win. You can win by either getting 100 CS, first blood, or first tower; whichever one comes first. You can also pretty much just pair up with
some friends in a custom game to recreate this game mode but at least Riot tried. After all, it’s the effort that counts!
