The delayed Star Fox Zero has a new release date: April 22nd, 2016. This was announced in the new trailer was shown off during the November Nintendo Direct. We also learned a couple of (I think) new things about the game.
- The remote controlled tethered robot that descends from the Gyrowing is called "Direct-i" (and has a very cute voice even in English)
- The Landmaster's flight mode is called "Gravmaster"
- The Landmaster can lock on to 3 enemies at the same time
- The Gyrowing is not a drone after all, but an actual piloted craft (Slippy is shown piloting it during the trailer)
- The cutscenes have a definite graphical upgrade over what we saw at E3
- No mention of Amiibo interaction or online modes, though
Here's a video of the part of the Nintendo Direct about Star Fox, including the parts after the trailer.
