Attention all Mario fans! If you act fast, you can get two Mario Tennis games for the price of one!

From now until December 17, you can grab yourself a free download of the Nintendo 64 version of the sports game if you grab the digital version of the newly-released Mario Tennis: Ultra Smash via the Nintendo eShop. Bargain or what?

Developed by Camelot Software Planning, Mario Tennis: Ultra Smash​ debuted yesterday (November 20) for Wii U in Europe and North America.

​The game feautures an online multiplayer mode, allowing you to go up against opponents from ​around the world in ranked play or jump into more casual matches.
