In Soldiers Combat, you have to blast your way past the assassins and reach the army tent at the end of each platform level. Blow up the vats and crates to collect special items. Most of the containers are empty, but some contain special ammunition, new weapons, and food. Shoot down the assassins to collect the three keys you need to complete the level. If you reach the end without all three keys, your commander will just send you back to retrieve them. Don't dither, because you don't have much time!
