Gladiator Dome 2                                                                                          
RR: 7.5
It's like Gladiator Dome - only there are two of them, joined by a short wide room, which makes the design very like Skippy's Star Command.  Luckily, the movement control is easier here, so you are more likely to be able to grab the weapon or power-up that you want.  I suppose this is in some ways an improvement on the original version - though really it is just an alternative that would have room for more players.  Two large spheres to fight inside means room for four or more players to have a whole lot of fun...so, nice idea, Mikesmaf!
