The map is similar to a game of deathmatch. You are inside a small area in which you battle three enemies who will use their best tactics to take you down. I suggest trying this on different skill settings which can be changed in the game options.
You will start off with only a crowbar. There are three more weapons available in the map, but they are hidden. Find them or you will most likely end up dead.
The soldiers have an armour-system which allows them to take serious amounts of damage before they die, but keep in mind that for each hit they take their armour energy is drained a bit, but it regenerates slowly. A fully drained armour can be fully regenerated in about 1.5 minutes.
The soldiers will also cloak and hide around the map, and will support their injured squadmates using a heat-system which tells the other soldiers how much fire the other squadmates are taking, and when it reaches a certain limit they come to his aid.
If you want a real challenge, try beating this on HARD (change manually in game options) I can safely say that this is possible for I myself have done it, and so have some of the beta testers
