Like Guardian, it is exclusively available through Operation missions, but can be easily accessed through the console.
In Co-op Strike, 2 players go against a staged fight against an AI controlled terrorist team in a story-driven scenario. Unique enemies like the Heavy Phoenix can be found in this mode. As the players progress, they will receive updates on the story from a voice over the radio, similar to Weapons Course.
The maps in this mode are designed specifically for Co-op Strike, having unique objectives and elements not found on other maps. The players do not buy weapons or equipment, and instead simply pick them up from the map, with the map providing a starting area for players to gear up.
The map is divided into several areas, and the players cannot progress to the next area until the current area is cleared out and/or its objective is completed. The amount of remaining enemies in an area is always announced by the player characters in the radio upon a kill. Dead players will respawn when an area is cleared.
Missions have their own time limit that starts when the players deploy into the map after leaving the starting area. The mission fails when both players die or when the time runs out.
Friendly fire and team collision is off.
The map prefix for these maps is coop_. It shares the same prefix as some custom community Co-op game modes.
At the end of a game, the players' scores are allocated. The remaining time, player accuracy, headshot percentage, and damage taken are all taken into account. There are also four Team Bonuses: No Deaths, Collected All Coins[n 1], Pistols Only, and Completed On Hard Mode[n 2][n 3] that award bonus points when accomplished. Players may replay to get a better score, and these scores are displayed on the Mission Leaderboards in the Operation Journal.
