Uncompleting the objective for each mission on Destroy All Humans are commonly avoidable, especially if you’re new on the game. For some reason, there are no restart mission when you’re trying to go to Mission tab, making other players unable to retry completing the objectives without creating a new game.
The advantage of completing the objectives is it gives you DNA points rewards that you can use to upgrade Crypto abilities and your Flying Saucer such us increasing the duration of disguising other human species to help you with your mission.
