1. No X-Ray vision of the enemies. The game will be a challenge. 2. Cool African Atmosphere 3. Large open world 4. Great selection of Weapons 5. Physics are great. Love the fire effects 6. Enemy AI is actually good. They will hide, take cover and help their wonded. Even when wounded they will take out a pistol and shoot you. This game is seriously underated and won't hold your hand. If you want to try it, wait for a sale and grab the Redux + Realism Mod. It will enhance the graphics and add a 1 hour real time timer for the checkpoint guard respons.
