Hi-Rez Studios announces the next patch for SMITE will add a new game mode to the MOBA. Here are some details on Arena mode:

The new mode, called Arena, is a very action-oriented, team death match and takes place on a brand new map with a Colosseum setting.

Arena is played 5 versus 5 with minions and side-objectives including buff camps and Gryphon Guardians. But rather than a single end objective, in Arena your team earns points for killing enemy players and minions with the first team to deduct 500 points from their opponents being crowned the winner.
