From B-Ball, a fairly small arena, with an airy open plan to it, complete with the chance to fall to a quick death if you miss your step on the way to the megapower. This is obviously designed for a fairly low occupancy rate, with only four weapons (scattershot, pulsator, triple strike, & hypershot). Rumour has it that a "rocket jump" might get you to a higher level, but that might only apply to a preliminary version that has been around for a few weeks. Some extra glass flooring makes the place less of a death-trap than it was, and I think this ought to play pretty well.
So, not a huge map, and not hugely innovative, but it works well...and, from some screenshots that B-Ball has published on his site, it looks as if, based on his experience on these early maps, he is moving on to some even nicer arenas. Two levels, plenty of metal walkways, elevators to shuttle you up and down...what more could we ask? A different version of this remix exists, DeathFan Remix 1_0, by Warbird, but is not generally available, and is not generally held to be any improvement...
