USGamer:
Operation Abyss: New Tokyo Legacy has surprised me. For starters, I'm surprised by the fact that NIS America is publishing the game in the U.S., yet it's surprisingly light on the company's trademark anime wackiness and fanservice. Aside from some too-revealing generic character portraits and a recurring character who aspires (poorly) to be a comedian, Operation Abyss is decidedly nuts-and-bolts in its presentation.
The PlayStation Vita has become a haven for RPGs, but there is one particular type that has really made itself at home on the system. People who love first-person dungeon-crawlers with turn-based battles and often customizable parties can find tons on the system. Developers like Experience and Compile Heart have taken to the system. This means people who enjoy level grinding and customizing characters have plenty of options to choose from when looking for a new game to play.
Operation Abyss: New Tokyo Legacy is an excellent dungeon romp through a near-future sci-fi Tokyo.Finish that high-school class quick, so you can gear up and dive headlong into a quest for missing students that'll lead you into fierce battle against bizarre enemies. Best of all, this dungeon-crawler won't make you crunch more numbers than math class! (Unless you're into that.)
