Modification allows your allies (your gang) to resurrect you.
If there is a member of your gang nearby, then when receiving critical damage with firearms or melee weapons, as well as in hand-to-hand combat, the main character will fall to his knees and begin to slowly die. All this will be accompanied by sound effects and the screen will gradually turn black and then red. If your friend manages to run up to you, then he will stick an adrenaline syringe to the main character. after which the lives will be restored a little and you will be able to continue the fight! If the screen has time to turn bright red before the ally runs, then the main character will die.
