Argo

Argo was made by Bohemia Interactive who is famous for the Arma game series. Developers offer to try this game for free to learn what it feels like to play at Arma3. In reality, it bears resemblance to the famous game franchise but lacks some key features, such as mods and the overall feel of a battlefield presence. The in-game 3D scenario editor was implemented instead. The editor is fun to tweak with and will deliver hours of addicting campaigns for sure. As for the gameplay, it's a standard first-person tactical shooter that is aimed to bring a life-like experience. The skill tree player progression allows the unlocking of new weapons and outfits. There are also 5 versus 5 multiplayer game modes (Clash, Link, Raid) and a standalone 10-player co-op mode for you to play along with your friends. All in all, Argo is an excellent Arma 3 tester which highlights its game mechanics and promises a lot more for the hardcore fans of the genre.
