War is hell – it's much better if you can avoid getting shot at. Actually, it's much better if the enemy never even knows you're there. That's kinda your aim in Commandos, to wage war without the enemy even knowing that's what you're doing. Well, not until that grenade goes off underneath them anyway.
You control your soldier directly, but you view the battlefield from above and can survey around the whole environment by switching to your binoculars. Yep, in Commandos binoculars even let you see through walls.
