At the turn of the fourth millennium, a new sport, held in "The Pit," offers entertainment to humans and freedom to its surviving prisoners. With a handful of prisoners under your command, you can design and manage your own editable base of operations; build defensive structures, traps, and weapons; and create beautiful gardens to please the crowd and protect your investment. Fight battles online in one-on-one multiplayer match-ups, or connect as a spectator to watch the mayhem from the front row.
