   Grenades travel in a sharp arc towards the crosshair.  They'll bounce until detonation (about 3 seconds after they're primed). Grenades also offer a large radius damage effect when they explode. With the hand held grenades, holding down the trigger will allow you to throw the explosive farther.  Holding down the trigger without releasing the grenade for more than three seconds will cause the weapon to detonate in your hand. 

   The launcher fires more quickly than the hand thrown 'nade, and will never detonate while holding onto it but each grenade does slightly less damage than when they are thrown.  Also, any grenade (launched or thrown) will detonate instantly upon colliding with a player or enemy. 

   The grenades are best used in retreat or around corners where an enemy's location is known.  Grenades should never be used to chase a fleeing enemy down as the shooter will probably be running right over loose grenades just as they detonate making it very 
likely for the player to kill himself. 

   The best way to fight a player launching grenades is to not pursue, but find another way around the map to maneuver behind the opponent.  Most maps in Quake2 allow the rooms to be entered from more than one direction.
