We've seen what Destiny looks like on PS3, and PS4, but what about Xbox One? Well. It's complicated.
The Xbox One beta for the game is not going to run in full, 1080p HD (it'll be around 900p). But the final game will.
Below is footage of the game running in said 1080p. Which you won't be seeing in the beta, but will be seeing in the finished game. If you want to get the finished game after playing the beta, that is.
