K.O.S.: Secret Operations

K.O.S.: Secret Operations (short for Kill On Sight: Secret Operations) is a free-to-play online multiplayer first-person shooter centered around battles between teams of special forces operatives. In all game modes, both teams must work to complete their own objectives while eliminating members of the opposing team. There are twelve playable classes to choose from (with only six available to start with), and each have slightly different bonuses to their weapons or equipment.

In one of the primary game modes, 'Search and Destroy', the red team must plant a bomb at any of the bombsites on the map and defend it until it explodes, or kill all members of the opposing team in order to win. Likewise, the blue team must kill all members of the red team and diffuse the bomb if it has been planted in order to win.

In another primary game mode, Team Deathmatch, teams battle it out for up to 30 minutes to get the most points, with points earned by killing members of the opposing team. Players who die during a match are respawned back at the starting location with a temporary invulnerability that lasts a few seconds to prevent enemies from spawn camping.

As a free-to-play game, K.O.S.: Secret Operations is monetized via a microtransaction system where players can purchase unique types of guns and other equipment using real-world money from the in-game store.
