Mutually Assured is one of the hardest Hostiles maps in the game, as the map is extremely small, making for very little time to take cover and heal. As well, Mutually Assured has the highest requirements for stars out of all Hostile missions: 50 kills are required for one star, 100 kills are required for two, and 150 kills are required for three. However, it is extremely easy to get to the Care Packages that spawn after every round, due to, again, how small the map is.
The player will start with a CZ75 that lacks attachments. The enemies that spawn will use the SPAS-12 at first, then use a combination of the MP5K and the Carbine with a Red Dot Sight, then later on they will use weapons like the M16, the AK-74u with a Red Dot Sight, and the M14.
