How about imagine being in a forest scene. There is a lightning storm beginning while in a battle with the hive. As you continue your battle heading towards the hive base you see a lightning strike hit a tree and causes a fire in the forest so you have to evade getting burnt from the fire and the hive. Also finishing the battle with the fire getting out of hand and you have to escape planet. That's my idea. Weather in destiny sounds cool. Gives a game more depth.
