Overview

The Mk2 hand grenade is a World War II era grenade used by the Marines in Black Mesa.

Grenades have a considerable blast radius that will also set off other explosives, so it is recommended that the user be aware of nearby laser tripmines or explosive barrels. Grenades can be cooked, and like other physics objects, they can be picked up after being thrown [1].

The player can carry a maximum of 10 grenades [2].

Primary Function

Throw a grenade. The grenade can be cooked by holding down the mouse click.

Grenades have a 2.5 second timer before the detonation. Failure to release the grenade before the timer elapses results in the grenade detonating in the user's hand. The timer resets when picking up a live grenade for the first time, provided it is at less than 2.5 seconds [3].

Secondary Function

Roll a grenade. The grenade can be cooked using this technique as well.
