Making out with a zombie is likely more arousing than playing this game...
For starters, the graphics are awful. I honestly cannot tell if they are supposed to look like a comic, or if they are just plain bad. In either case, I'm not impressed (except maybe at how anyone can release a game this ugly in 2013).
Sound is pretty meh. Nothing inspiring whatsoever.
Gameplay is some of the worst I've played in a good while. It had some interesting ideas, but fudged all of them. Melee combat is you punching a zombie in the face 3 times until they simply fall over. Alternatively, you can sneak up on them and stab from behind, watching the same animations over and over and over and over...
If you get grabbed by a zombie, expect a good gangbang out of it every time. As you kill each zombie with a QTE, a new zombie will immediately take its place, and you will keep killing them with the same QTE over and over until either your or them are dead. Most likely you.
Gunplay fares little better. The controls are TERRIBLE! There is some kind of weird mouse smoothing/acceleration going on, meaning you can never aim properly. It basically the same feeling you have when you have been drinking too much and desperately needs to find a bathroom. I do not recommend it.
Oh, and every time you fire your gun you will be swarmed by more walkers than you could possibly kill with your limited ammo, so it's better to just to bother using them at all.
As for the story, I don't know what to say. You play as Daryl from the TV show, save your brother Merle from prison, and then you go do stuff... or something. I have no idea really, I don't care. The writing is awful, there is no depth to any of the characters, and the dialogue between Daryl and Merle is borderline retarded.
Don't buy it, don't play it, don't eat it. Your stomach will most likely reject this POS anyway.
