Shock Troopers also have the ability to regurgitate and throw spore grenades, which they tend to use against distant or concealed enemies. If it nears a player that already has a Shock Roach, it will attack in a similar way to a Headcrab before dying. The Shock Roach cannot survive without a living host for very long if its Shock Trooper dies, it will detach itself and pursue a new host. The Shock Roach fires bolts of electricity, which it constantly recharges on its own just like the Hivehand. Shock Troopers, as their name suggests, primarily use electrical attacks through the use of a weapon known as the Shock Roach - a living creature, similar to the Alien Grunt's Hivehand. A Shock Trooper is first briefly glimpsed in the chapter 'We Are Pulling Out', and they start to appear as common foes beginning in Crush Depth.
