Welcome to the world of The Passing. It's 2007 and a surprise awaits Jonathan. The world is a decayed shadow of what it once was, and faceless creatures, The Stalkers, roam the streets. In The Passing, the protagonist, Jonathan, your typical teenager, is not a hero: he's just trying to survive, hoping that there are still some people left. It's The Passing of all life on earth. Because misery loves company
The Ramming Stalker was going to rush forward in an attempt to knock over the hero. In the revised version, the Ramming Stalker is a humanoid with a ridiculously large head which it swings around to cause damage.
Reminds me of the Charger to be honest, both in looks and activities.
