Titan's Repose is 3v3 or 5v5 battleground. There are also Practice modes available.
With a Domination Tower serving as a focal point for capture, teams will be constantly skirmishing in the middle of the map. Capturing the tower awards your team a steady flow of points, as does defeating enemies.
The winning team is the team with the most points at the end of the allotted time. You can also check the scoreboard at the end of the match for bragging rights!
