The traditional pull-the-pin-and-watch-the-explosion weapon, the Grenade can be as useless or as effective as you make it.
Grenades. You know them, you love them. There isn't a lot to say about them, since they are so well known and used. Either way, grenades are used mainly to cause some serious mayhem with groups of enemies, or even single enemies. They are usually fatal, depending on how close your throw is, and they are put to best use in clearing a group of enemies to easier-to-handle numbers. The grenade will explode a few seconds after the pin is pulled, so you'll have some time to aim them, and to get out of the way!
However, some enemies like to run away when in the prescence of a grenade, so throwing one doesn't guarantee fatality.
