Welp... This game is something else... I mean, there is alot of diversity of weapons and customazation of clothes for the insurgents and the security forces, the concept doesn´t change, wich is good, (Its Insurgency all right), The gameplay itself its more realistic than the previous Insurgency (Its means that they run slower and reload, change weapons slower).
There is only ONE bad THING... YOU NEED TO ADAPT yourself to this game (Play it for Hours), because you will join with people that have spent quite a while in this game and thats why you need to waste some hours of your life to fully understand how to use covers and comunicate with your teamates (most part of the players don´t talk, so yeah)
Anyway... The game is good, you just need to be patience, its all you need to do.
