Battle Cry Effects

Camaraderie
Camaraderie indicates the trust and bond between you and your comrades. Higher Camaraderie results in stronger effects in Snake Sync Mode.
Camaraderie increases through using CO-OP IN, Snake In, and performing CPR on comrades in a near-death state. Conversely, accidentally shooting or injuring a comrade makes it decrease.
Camaraderie earned in a previous CO-OPS gained will be maintained in future CO-OPs games with the same comrades. However, if you don't play with them for an extended period of time, your level of Camaraderie will revert back to its original state.
