Conflict Global Terror / Storm was the last 'real' Conflict type game with 4 playable characters doing almost the impossible to stop the bad guys, whoever they might be. It was also the first time the campaign took the player around the world, and not just one set piece. On the highest difficulty, the game can be unforgiving, and it will not hold your hand. A mission run could end just because you told your team to follow you around the corner where a tank was waiting.
Out of all the Conflict Series games on PC, this is the only one that has coop multiplayer, making it unique in that sense. Since the game has not been publicly sold, the multiplayer is almost non-existent. A special group of diehard fans have been trying to keep it alive and its admirable. Hopefully, this game can be revived so we can play it with friends.
