Just a few weeks ago we announced that Tank! Tank! Tank!, the fun but flawed multiplayer title from Namco Bandai, became a free-to-play title on the Japanese eShop. You'll be glad to know then that this week Europe gets in on some of the tanking, ape shooting action too, as it gets confirmed as a free-to-play title in Europe.

Looking to save yet more money? Then fear not, as Trine 2 and Chasing Aurora get price reductions on the eShop, which is surely good news for those of you trapped at home by fatal snow. 

Finally, the 3DS gets another VC classic in the form of NES title, Castlevania, a demo of 2 Fast 4 Gnomz and two retail titles, Mahjong 3D and Shifting World. Scroll down for full details, prices and videos of this weeks downloads.
