These features are already included in IREnFIST, you do not need this mod if you have InF installed.

Makes cops harder to dominate, exactly like in older PAYDAY versions.

Instead of always surrendering if they're missing any health, there is now a wide variety of factors that will affect their surrender chance. Catching a cop with their weapon down/reloading, or catching them from behind will significantly increase your chances. Wounding them enough will also increase the chances, as will shouting at them when the rest of their squad is dead.

Some units are easier to surrender than others. First responders and HRT's will surrender more easily, while guards will surrender even more easily still.

The host must have this mod installed, it will affect all clients. Using it as client has no effect.

Thanks to Kuziz for giving me the exact surrender presets that cops used in U37.1.
