"Deluge of the Destruction of Mankind" Timeout
So I just got the latest version of Marine Benefit, which gives all the bosses "Omniverse" spellcards, which are basically Last Words.
And to my surprise, it's the utterly forgettable Miyo Amazu who has one of the hardest ones.
EDIT: Here's how to play the latest version of Marine Benefit.
Follow this link: http://rgbxyz.org/th_kaikeidou/top.html
Download everything in the orange boxes, put them in the same folder.
After that, make sure you change your system locale to Japan, as detailed here: http://windows.microsoft.com/en-us/windows-vista/change-the-system-locale (it's for Vista but 7/8 haven't changed it much). If you try playing this version of MB without changing the locale, it will lag to the point where 40 FPS will be fast.
After that, if you want, you can use the config to set it to fullscreen, since it's windowed by default. Select the option on the right in the top row on the config, and it will play fullscreen.
