Spike Grenade

Overview
The Spike Grenade is a curious grenade-like device of unknown origin. It operates similar to a standard grenade (IE, being thrown and exploding on a timer), however, once it's timer goes off, the grenade will abruptly burst into a massive spray of bolts, heavily wounding and puncturing whatever or whoever the bolts came into contact with.

Unlike the other grenades available, the Spike Grenade cannot be dropped with a secondary attack; it must be thrown via primary attacks.

Acquisition
The Spike Grenade appears in Route Kanal, in a Combine controlled outpost. It can be found inside an item crate next to another crate, which are beside 4 large shipping containers; two red, two orange. The containers are to the right of a door the player walks through, right after a small stairwell.

If it is missed there, it cannot be found again.
