If you love military-themed shooters, Argo is a pretty solid game to play. After all, you'll get to experience a bit of the famous "Arma gameplay" for free.
Counter-Strike: Source
Counter-Strike: Source is the second installment in the incredibly popular MMOFPS franchise, Counter-Strike. Despite being a rather old game, Counter-Strike: Source still manages to hold its own in this day and age, with some even claming this game is so much better than the more recent Counter-Strike: Global Offensive or CS:GO. Unlike CS:GO, this game doesn't offer buyable skins and the most important thing - the community is definitely not as toxic as those you'd find in the CS:GO servers. Although the game modes can be rather limited, you can easily find some really good new ones in modded servers.So, if you're looking for the Counter-Strike experience without all the hate that most new players will get, this might be a good game to start.
