The primary mode of the Grenade uses a four-second fuse, but can be "cooked" by holding down the trigger for a short while. Be careful when doing this as it will detonate in your hand if left too long, generally causing instant death.
The secondary function of the grenade causes it to bounce uncontrollably off surfaces until it comes close enough to a player, and then explodes. This player can often be the one who threw it unless they are careful, so throwing it into a room and shutting the door can be a good tactic.
Shares its model with the N-Bomb, though coloured differently.
An updated version of the trusty grenade. Can be thrown with a four-second fuse or used as a bouncing proximity bomb.
The first appearance of the Grenade is actually dataDyne Extraction. If you get to the elevator without being hit, you will soon find a guard with a keycard to Cassandra's office. In her office there's a single grenade on the table. Later, the guards in Area 51 tend to carry them.
