The fight scenes aren't bad, but aren't great. Nowhere near as good as the old 'Death March era' ones, but far from the worst I have seen from Giga. The hamster squeaks are still there - along with a lot of lingering on twitching/moaning/arse-up zakos (though there is more gasping for breath and laying there open-eyed, implying they are dying rather than passing out). The costumes are quite good though, and the girls put a good effort in.
The obligatory accompanying 'zako torture' video is utterly bizarre even by Giga standards. Rather than having a monster-costume punish the zako for failure, it basically consists of the 'fat Batman and Robin' heros (from earlier videos) forcing the zakos to have oral sex with them for nearly 40mins. All in all its rather disturbing and unpleasant. However one part literally defies any rational explanation - toward the end the brainwashed heroine comes in - and subsequently somehow grows a penis and joins in the assault on the zakos. I have literally no idea what they were thinking...
