Earth Defense Force 6

Did you want more weapons? Check. More vehicles? Check. More enemies to kill? Super check. You've got well over 100 missions here to chew on with much replayability like the previous titles without question. On top of all of this the plot this time around is much more interesting than before. Rest assured when this gets a Western release I'll be double dipping on that! EDF!!

Its more EDF! What more could you want? It has improved lots of things over 5, some nerfs were handed down, Air raider got a bit of a bonk, but over all things feel really good. Progression feels better (but works the same way as in 5). The plot is even more bonkers than 5, you can follow the big points using google translate video mode on a tablet or smartphone.
If you liked any of the EDF games you will definitely like this.

EDF6 has some nice improvements over 5, including smoother graphics, more environmental detail, tons of levels, and completion progress being shared between online and offline play (which hasn't been done in the main series since EDF2). The menus and dialog are all in Japanese, but Co-Optimus has an English menu translation guide that makes navigating menus easy. If you can't wait for the official English version of the game, the Japanese version is totally worth picking up and will provide hundreds of hours of fun.
