Caliber has over 60 operators with 4 classes such as Support, Assualt, Marksman and Medic. It is a free to play steam game that is team based, third person shooter.
It has PVE, PVP, and PVPVE game modes. Each operator has unique and different abilities. If you play the game long enough, you can end up getting perks for your characters which in the long run is a great thing.
It is a clone of rogue company, call of duty and CSGO. I actually enjoy this game and highly recommend it to anyone who likes these kinds of games.
