The Longest Yard                                                                                   
RR: 6.5
Some of these arenas make sense as actual places, and some just seem to have been cobbled together.  This is another of the floating-in-space concoctions, as ugly as Injector - but thankfully more practical.  There is a large flat area with walls at each end and a cunningly-directed bounce-pad in the middle - hit it right and you can snag a shield.  There are higher bits, and outer bouncers to bring you back in if you hit them just right, and even a little bit of teleportation, so it is all pretty invitingly playable.  Some of the trickier moves just do not seem worth attempting, unless you enjoy falling off into space, but it is all well worth investigating.  A Captain Mellow production!
