So this one is improved over the first game. In this one, you have 4 campaigns in this one. You can play terrorist, counter-terrorist, post-nuclear, and blood-game campaigns. The first 2 are scenarios you have to get out of while the other 2 are based on games I've played. 3rd campaign is pretty much inspired by fallout while the 4th one is inspired by the game blood. You can't shoot through walls like in the first game which makes this game more challenging but I managed to get through all of them. I give this a 9 out of 10.
