Grenade Throwback

Grenade throwback is a gameplay mechanic that can be found in almost all modern day shooters. Usually, the game tells you where a grenade is thanks to a grenade indicator. When a grenade is close enough for you to throw it back, the game will tell you this by showing you the button that you must press to throw your grenade back. To excell at the art of throwing back grenades, you must have quick reflexes and be paying attention to the action. The best way to fight against people throwing back your grenades is to cook your grenade before throwing it.  
Grenade throwback is only possible in video games. In real life, a soldier who would stumble upon having a grenade at his feet would or jump out of the way or kick it away from him, with very little chance for survival.
