The Denpa Men: They Came By Wave is one of the 3DS' quirkier exclusives, a downlodable RPG that makes you search for new party members hiding in Wi-Fi connections (and getting very odd looks while doing so). The sequel, Beyond The Waves, has been dated for a May 30th release on the eShop, costing an affordable £8.99.
Alongside gameplay improvements, the scope and scale of the world has been increased with the addition of towns, oceans and other features. Brilliantly, you can also transfer Denpa Men from the original. More details in the deliciously odd trailer below.
