It's pretty typical as far as adventure games are concerned. You control a main character, explore the environment, talk to people and solve puzzles. There are some quick-time-events when it comes time to kill zombies.
Overall, the game does a good job of involving you in the story. There's a demo on PSN you can check out.
It's more of a point and click adventure game than anything. Think Monkey Island, Sam and Max, etc.
You do have direct control over the main character but you just as easily could take that away and the game would be pretty much the same. If you are interested in a well told story in the Walking Dead universe than pick it up. Story is the key word there... it's mostly all talking to other characters and some simple puzzle solving. If you are looking to mow down a bunch of zombies go grab Dead Rising.
And if you are not familiar with the Point and Click genre by all means get the Monkey Island Special Editions. I will guarantee satisfaction! --- XBL: Scooby MaroonPSN: GhostOfJAWS Wii: A bunch of numbers!
Thematically it's basically survival horror but gameplay wise this is definitely adventure game. --- A second ant? No, no, it's his brother, avenging the death of his twin. It's his twin brother! I'm going to follow him home...kill his whole family.~Space Ghost
