Hover

According to the store page Hover is a fast-paced single and multiplayer Parkour game in a futuristic 3D Open World. So for the online multiplayer, yes you would need a gold subscription to play, but for single player, you shouldn't need one.

If you want to play multiplayer, then yes you will need an Xbox Live Gold subscription.

That's called miracle resonance. When someone uses a miracle it basically leaves an echo in another person's world. When you use miracles near that, they'll be more powerful. If you pay attention you can tell where people spammed Wrath of the Gods, haha.

I remember when I first saw it I thought it was a glitch. I thought it was the circle that you see when you target an enemy. lol

Also you can usually see one in the forest near a cliff. I figured people were using Emit Force.

Always wondered what these were for.
