Etrian Odyssey 4: Legends of The Titan is releasing on the 26th of February. However, if you own a 3DS and still are not sure whether to pick up this game or not we have some good news for you.
Atlus has confirmed that it will be releasing a demo of the game on the 3DS e-shop on the 7th of February. Furthermore, all the progress you will make in the demo version of the game will be transferred over to the full game if you decide to purchase it.
The demo is quite a big one too, letting the players play the whole first dungeon of the game along with some side quests as well. I see no reason not to download it if you happen to own a 3DS.
