Muhaha... too hard? I really screwed down the difficulty for you judges so that you are able to reach the exit without problems Laughing
Well you have to zoom-out fully and go left at the start if you want a chance to reach the ammo camp, and later, you have to learn to fire rockets preemptively before the enemies become visible, otherwise you're toast
(static cannons are the ones doing most damage IME, and unlike with enemy tanks, I couldn't find any way to avoid their shots, so you've got to kill them fast).
