Ah, the Year of Luigi. It's almost over, but Nintendo still has a few surprises in store, like the all-new Dr. Luigi coming to the Nintendo eShop.

Like the original, Dr. Mario, Dr. Luigi tasks players with eliminating viruses by matching up color-coded pills. There will be multiple levels of difficulty, and there are going to be special attacks in the multiplayer mode. Additionally, Dr. Luigi will have a unique mode using L-shaped pills.

This new puzzle game will offer Wii U GamePad compatibility and online multiplayer. There will even be a classic Dr. Mario mode included, too. Dr. Luigi will be available for $14.99 on the eShop on Dec. 31.
