Eagle Flight was one of the VR games on show during Ubisoft's E3 conference. The game puts the players in the perspective of an eagle and lets them fly around the city of Paris which has been reclaimed by nature.
We got to see some gameplay at the conference, with a co-op game of capture the prey (flag.) Here we saw two teams, all in VR, playing against each other. We saw flight tactics and shooting at enemies. Wind physics can be used for speed and cover from buildings and nature will help you hide from your opposition.
It has Oculus Rift support, but does not yet have a release date as yet. See it in action below.
