Known as the more transaction-friendly Akiba's Trip 2 in Japan, the Acquire-developed adventure is set in Tokyo otaku haven, Akihabara. There, a bunch of vampire-types called Synthisters are having the locals for lunch, but you can stop these monsters by exposing them to direct sunlight. Apparently, the best way to get some sun on Synthister skin is to get that skin out in the open. In brief(s), you're stripping vampiric demons down to their underwear so you can send them back to the nether regions - sorry, Netherworld.
According to a Siliconera translation of Famitsu's report, the new PS4 version offers enhanced visuals and faster load times, and it can also display more characters on the streets of Akihabara. It's due to hit Japanese retail shelves on July 3.
