To do so, he must activate the steam vent (located near the creature), the main pressure valve (also located near the creature, and to be accessed thanks to the hand-held Barnacle and Spore Launcher spores on the wall, since the ladder to access the valve is broken) and the primary pump gearbox (located in Waste Station 02, another area, and by using an emergency override button) to unlock the toxic waste arrival, then release the toxic waste with the waste flush button, flooding the room with toxic waste and killing the creature. In that area Shephard must use toxic waste to defeat the Pit Worm. It also includes two garbage compactors the G-Man can be seen in one, observing Shephard's movements. That area comprises several Waste Stations and a main Toxic Disposal Basin, where Adrian Shephard discovers the Pit Worm. The other side leads to the Topside Motorpool, linked to Waste Processing Area 3 through a large tunnel leading to an underground parking lot where the Gargantua is met.Īn underground section of Waste Processing Area 3 is visited in Opposing Force. In the section seen in Half-Life can be found a Tactical Map originally manned by Cooper, a now dead HECU soldier, and used by Gordon Freeman to defeat the chasing Gargantua and clear the way ahead, leading to the Sector F.
