The fifth Bonus Mission is a tricky version of the first Training Camp, becaue it happened nighttime. You are given Lupin and Inferno as your Commandos. Your mission is to kill all of the soldiers in the map. The tricky part here is that, even though it is nighttime, there are spotlights guarding some areas so be careful. There are also additional soldiers patroling. With a good tactic, it will be finished easily.
