Delta Force 1 was the only of it's kind when it released, with bad-ass missions and great action. A.I. is not great, sometimes you will find somebody running into a wall but trust me when I say the game is still very challenging. The maps in Delta Force are VERY big, the terrain was randomly generated when maps were made making some of the maps look realistic with hills. Sound engineering is also great, with perfect ambient and weapon sounds. The game has 40 missions in total, across Peru, Chad, Indonesia, Uzbekistan and Nova Zemlya. When you start the game up for the first time you will have 2 missions unlocked in every location, once you complete a mission, new one will appear on that same location. The game doesn't have any difficulty regulation - one mission can be very hard, the next one easy however I this isn't a bad thing in my opinion, since Delta Force is a military game.

Delta Force is the start of a long running series that originally released back in 1998. Delta Force gave a hybrid of the more action packed shooters and the more tactical Rainbow Six. When starting a game you could cycle through a few appearance options for your face, choose your loadout, and then start one of the campaigns that would have you in a large open area where you would have to complete your objectives. Environments put you in deserts, jungles, snow, etc and the scoped weapons allowed you to fight targets at long range. Night missions allow you to make use of night vision and some stealth could be used if you sneak up and attack enemies with a knife. Both you and enemies could be killed in one hit, keeping the damage model from more tactical shooters but allowing you much more accuracy with your weapon, faster movement, and the ability to fight your enemies alone. Some missions did have other allied soldiers on the battlefield but they were often killed and you didn't need them like you would in other similar games. The game is somewhat hard to recommend now when you have titles like Ghost Recon, Operation Flashpoint, ARMA, etc but if playing through older games that tried something a bit different interests you then it's not going to cost much.
