This unpleasant-looking thing is a "Carrion". They're malicious roadkill (that are still alive and very dangerous, despite their broken bodies) which can be encountered in Konami's 2007 Silent Hill: Origins video game (said software was originally titled as Silent Hill: Zero in Japan, because, chronologically, it's a prequel to the first Silent Hill). Carrions come in two sizes, large and gigantic, although both version behave the same.
The supernatural forces that hold sway over the cursed town of Silent Hill like to take an individual's emotional baggage and manifest those feelings and ideas as twisted creatures. The Carrion represents Travis Grady's (the game's protagonist) revulsion and guilt over the many animals that he has seen killed along the roadside, and run over himself, during his career as a trucker. Although the consequences of their attacks on Travis are all too real (I.e., if a Carrion kills him, he really dies), these creatures don't truly exist, as they're phantasmal constructs that generally only Travis can see and interact with--if you or I were in Silent Hill at the same time as Travis, we might observe him assaulting or fleeing from what appeared to be thin air, or, worse, we might see an all together different monstrosity based on our own psychological hang-ups!
Provided that he keeps his distance, Carrions will often ignore Travis, content to just sluggishly, and mindlessly, drag/push their mangled bodies about (this pitiful means of locomotion is probably a direct result of multiple bone fractures and/or partial paralysis). However, if Travis does draw near, the Carrion's memories of its death under the wheels of human drivers will awaken, and, enraged, the beast will vigorously attack, seeking revenge. As you can probably guess, trying to engage one of these abominations in close quarters combat isn't the best idea, as they can move very swiftly when they want to and have the size and power to toss Travis around like a rag doll (that said, turning off your flashlight, sneaking up behind one, and striking at its' defenseless posterior is a tactic that can work well). It's wiser to just avoid them altogether in wide open spaces, but, if you have to engage a Carrion (and you will, as they sometimes block narrow passages through which you must travel), it's better to use firearms, or other projectile weapons, to hit them from a distance, rather than provoking a direct confrontation in which you will likely suffer injury.
Instead of feelings of fear or revulsion, these monsters just make me sad--I've seen far too many dead animals smeared across the asphalt in my life. I've never driven over an animal myself (not because I'm some kind of awesome motorist or anything, I just don't drive), but, I still have the misfortune of seeing the results of those mishaps on a regular basis, as I do a lot of walking/hiking along the local roads and highways every week. That waste of life is always a depressing, and often disturbing, sight, but, short of never leaving the house, those gory discoveries are inevitable. I understand that hitting an animal is often unavoidable, and that attempting to swerve around them can be dangerous to both you and other drivers in crowded traffic, but, on the other hand, I've also known individuals that purposely and gleefully run over animals whenever the opportunity arises, even swerving out of their way to hit and kill them, and proudly boast of it after the fact. I daresay that meeting a Carrion in a dark alley would be exactly what that kind of person deserves.
