Europe will be getting a demo version of Star Fox Guard, a downloadable version of Star Fox: The Battle Begins animation, and the training missions for Star Fox Zero, including training for the Arwing, Landmaster, Walker and Gyrowing. Any save data from the Star Fox Guard demo can be carried over to the full version when purchased. The animation and Star Fox Zero training missions are a single demo package. Both demos can be downloaded for free in Europe on July 14th. No word on these demos coming to North America or elsewhere just yet.
The information appears to be from a press release, so the original source is not publicly available. However, nintendo-insider.com posted the whole press release on their site.
Thanks to Hope(N Forever) for the heads up!
