Shocker (beta) & Final Shock
Now, I haven't read the no-doubt excellent Gen13 comic, but from the covers, our friend Rainmaker looks awfully cute. So, why this terrible stinker of an arena? Having the structures transparent is a nice idea, and the uneven grey ground with lots of weapons on is reasonable, while the presence of an empty "skin" that can give you 25 points (in the beta at least) when you "frag" is at least, um, okay. But why are there so many places that have no features to them at all, just a bit of open ground, where suddenly you are dead? You can't avoid them, and it makes any sort of play, well, a non-starter. Usually, this means the mapmaker has forgotten to hit the "Rebuild" button...
In a word, avoid!
