I remember speaking to Cobra about this certain issue and Tomer also raising the point of perhaps creating a new Item such as the 'Team Heal/Armour Points'. It's when a player throws a grenade and like the 'ADAM (--)', it explodes into a circle on the floor with a different element. However, within the circle there will be a time limit and a certain grenade either "healing/recovery" on the floor when you stand on it. It is still yet to be discussed.
