This map is a customized map, you first pick a hero from 1 of 3 taverns [STR,INT,AGI] and fight with creep waves of Footmen. The game and its idea is from the Mini-Game for the MMORPG RuneScape Castle Wars. You get points to your team by capture the flag, killing heroes.
NOTE: This map is pending, its NOT finished, visit the forums or these two links about the ideas and help recruitment:
