F.O.E stands for Foedus Obrepit Errabundus, which is latin for "the vile, wandering one sneaks up". I almost knew that from memory, just had to Google to check the spelling.

Basically, incredible ridiculous and often cute monsters that can KILL YOU IN ONE HIT if you are not prepared. Which you most likely will not be the first few times you encounter it.

I liked the style of the game and how everything was put together, but I don't really want to play it :P It had bonus points for having Trauma Center's Dr. Hoffman in it. I think Etrian 2 features Dr. Stiles from Trauma Center as well.

The official website has some comics exploring the new classes and other game elements. Did it for the first game too.
