- PDA Description

The Grenade is a weapon in Doom 3. They can be found for the first time in the Administration level inside the code locker near the entrance and in the communication room.

Combat analysis
It is an explosive weapon that deals splash damage. Grenades can bounce off walls but will explode on contact with a monster. It should be used in corridors to kill zombies around corners or behind cover. Do not use the grenade at close range, as the explosion can hurt the player. Also, do not cook the grenade for too long, or it will explode in the player's hand, killing him.

Tactical analysis
While grenades are handy for flushing out Z-Secs, it is most useful when thrown directly at an enemy. Imps, Vulgars and tentacle Commandos will die if hit by one, making it a great alternative to the Shotgun if the player does not, or can't, get close enough to a target for the Shotgun to be effective. In addition, it can kill multiple Zombies with one explosion. Slow moving enemies such as Mancubi are also inviting targets.

A major problem of grenades is that they bounce everywhere, and 9 out of 10 times will end up far away from the intended target. To counteract this, just cook the grenade, or hit the monster full on.

Grenades are also useful against Revenants before obtaining the Rocket Launcher because they deal a similar amount of damage as the Rocket Launcher.

A last ditch tactic that you can use if you're crazy or desperate enough is to cook off the grenade to where it will blow up in your face, however this is ill advised as a single grenade can kill you if you are not careful, but will be devastating if you know what you are doing.
