The graphics aren't that bad as many people say. They fit this genre/gameplay. The atmosphere is fantastic. With my trusted flashlight, I ventured through all sort of locations such as a police station, hospital, grocery store, park, etc. I believe the locations are fixed on day/night cycle. Walking through the park level was at night while visiting the a town was in the day.
The gameplay is very similar to dishonored. Combat is more melee focused. A melee weapon has light/heavy attack functions and walkers can easily be killed from a stealth kill. Walkers can only be killed with 4 light or 2 heavy swings to the head. You also can shove walkers off with the RB button just in case you need some breathing room. Now if you happen to get caught within a walker's grasp, you will go into a quicktime event where you need to aim at the walker's head and stab. It's not easy at this point since the camera is shaking, your view is distorted, and your health gradually drops a bit every passing moment. I found it frustrating when I had like numerous walkers on me so I had to do that quicktime event one after another.
Using a firearm is only means for last resort because ammo is scarce and attracts more walkers to your position. So even if you decide to kill off every single walker in a level, walkers will eventually respawn back. Sometimes it's best to avoid fighting so you need to be smart against walkers. There are distraction items to be used against walkers. For example, throwing a glass bottle at desired direction or activating a car alarm to sway off walkers.
The main goal in levels are scavenging for fuel, food, ammo. and weapons like a rabid dog. Sometimes you will encounter survivors that need help as well. In return for completing their quests, they either will aid you by joining your group or give supplies. Unfortunately, you cannot bring everyone to your group because of limited car space. Sometimes you will change vehicles that can hold 2 while others only hold 1. Not to worry, the survivors don't have much personality after joining up. Between levels, there are some planning to do like picking one of three routes to go. One route uses low fuel but high chance to get more supplies and vice versa. Entering a level, you can choose what equipment to bring, command your survivor to find supplies, store what supplies at the car.
The sound is good. Spooky music plays when something is about happen. I actually jumped at times because I never expected what was going to happen. The voice acting is good. Sometimes when you stealth kill a walker, your character will make witty remarks, "Suck it", "Di*khead". That was funny.
In conclusion, I believe this is a good purchase for $40 at amazon. This game has replay value unlike the TT version. Think of this game as an improved Land of the dead on XBOX.
