How does Batman glide in the Arkham video game series?
I'm really curious about how that works.
Any answer goes.
Christopher Nolan's Batman also has this ability.
If they use the same "technology" to achieve this then, as explained in Batman Begins the cape is made of a Memory Cloth which uses electrical charges within the material to make it rigid enough to glide and fly.
As you can see from this video, she just spreads her cape out and kinda uses it as a hang glider/parachute to glide around.
