This week's issue of Famitsu magazine includes a small blurb on a title called Yuusha no Kuse ni Konamaikida G, a new PS Vita puzzler that, from the sounds of it, is an upgraded edition of the similarly-named puzzle game released on PlayStation Mobile last year.
The game, an offshoot of the Acquire-developed series titled What Did I Do to Deserve This, My Lord!? in the US, involves using a shovel to dig through onscreen blocks, then summon monsters onto the free spaces in order to defeat the heroes threatening your cool monster lair. It'll be free to play (with assorted extras you can pay for), allow for four-player competitive matches, and generally seems to work a bit like the game sections of Puzzle & Dragons.
No release date was given.
