A rather bizarre crossover is going to take place in the form of free DLC for Sonic Lost World. A Legend of Zelda theme is planned for release tomorrow.
A trailer for the new DLC has also been released, see for yourself. This marks the second time Sonic Lost World had some form of a crossover, the first was a Yoshi theme. Sonic is dressed in Link’s garb, collects rupees, and fights off all sorts of monsters from Link’s world. You can even see Link himself in the footage. The DLC is available only for the Wii U version of Sonic Lost World.
