see you and run in different directions An easy way to kill them
all is before going into the room hide behind a wall and toss in a
regular grenade When the grenade explodes it should kill them
all because they might not notice it If any are left just shoot
em of you could through in a flash bang grenade and run in shoot
them only do the flash bang one if you have low health If
multiple enemies are behind an object through a grenade at em but
make sure it goes BEHIND the thing theyre hiding behind If the
grenade explodes in front of the thing no damage will be done to
