Cross (beta)                                                                                                              
RR: 7.0
A refreshingly simple idea from Black Dragon this; four circular rooms, each with two triple strikes and two rocket ammo packs, meet in a central "cross".  What else is there to say?  The entertainment here relies on who is fighting, but it ought to be a fast and furious fight in "rocket arena" style, and you may well get more enjoyment here than in an arena that took twenty times as long to build.  It all depends on what sort of game of NAB you want to play.
