Just another average chapter of Gantz frankly: snail slow pacing, fodder characters unceremoniously killed off (except for the guy who looks like Izumi), needless double paged spreads that just slow down the action even more and ending on a cliffhanger of Kato and Kei teaming up to beat the alien, considering that they're the only two characters that seem to matter anymore (and it remains to be seen just how useful Kato will end up being). It was cool to see Host Samurai again at least, but it still sucks he wasn't given anything cool to do since the Nura arc.
It feels to me that Oku has just gotten tired of writing this series and has just been padding the arc out to an unsatisfying conclusion (in fact he'd probably would've rushed it even further if it weren't for just how big of a cash cow it has turned into). In any case once this series ends, so will my obligation to keep reading it. It was a fun, mindless ride before the aptly named Catastrophe arc began.
