DLCThe price gap between the first and second tier is pretty big but I don't really mind as I can get Arma 2 and 3 for the price of Arma 3 on steam sale.
The first tier imo is a must get even if Arma Tactics isn't really that good because Arma CWA has the best singleplayer campaign in all of the Arma games
So get packing men, we are going stop being maggots and become soldiers!
Oh I almost forgot, they are also including a total conversion for Arma III called ''Project ARGO''
It's focus is to bring 5v5 competitive objective-based fighting into the game (making it kind of like Counter-Strike or Rainbow 6 Siege but
realistic)
Also its totaly free, no payment required.
