This was an improvement over the original Delta Force back in the day, however, if you would play this game on any modern system now the game will look worse than the original Delta Force. Other than that the game is awsome minus the ai that gets hung up on walls and has "eagle-eye" vision that can shoot you from a kilometre away.
Also note that if you have a modern operating system, just be aware that the game crashes a lot and the hardware support for this game is abysmal in every way possible. Only a handful of chipsets will run this game properly in Direct3D mode (providing that you also have the right drivers with it).
In software mode the game just looks like puke garbage with half of the polygons on the character's weapon model missing while buildings sometimes disappear in plane f****** site; that also includes enemies.
If the above doesn't stop you from playing, then it's a great game and you should play it.
