In UndyingNephalim's ongoing development of fangame Star Fox Event Horizon, he presents this new CloudRunner Fortress level. An alternate path to the Walled City, a level we already covered, it's a chaotic scene that sees Krystal and Fox riding on the CloudRunner Kyte over the CloudRunner Fortress as they defend it from SharpClaws and even their own people. Voice acting hasn't been implemented in the level yet, but one of the things it does have is other forces than the ones you are actively fighting making actual progress through the level. Basically, stuff is happening even if you the player are not involved. Pretty detailed!
