Autogun



The Auto-Gun is a stationary Combine turret seen only in the chapter "Under the Radar" of Half-Life 2: Episode Two. It was used to stem the flow of new Zombies pouring out of City 17 as well as blocking supply runs to White Forest. It had three blue search beams that behaved like Overwatch Snipers (with their obsession with killing birds), but fired a much more powerful weapon which could drain the player's health in only a couple of hits. It can only be defeated by sneaking around behind it and dropping a Grenade into its control systems.

The black box attached to the back of the Auto-Gun sucks large amounts of air into the weapon when the panel is opened which could indicate that the weapon is Plasma based, this would explain why the zombies hit by the beam also catch fire as well as breaking in half.

It's also the remaints of the Combine Guard cannon from the Half-Life 2 Leak
