Dying Light is an open world game filled with zombies of many kinds, from the easier to handle Biters to the terrifying Virals that are agile and will try to dodge your attacks. In order to take down the vast number of zombies that the game throws at you, you may have to get creative. The game allows you to create your own weapons from various things that can be found throughout the city of Harran, leading to a vast amount of ways to take down zombies with a vast amount of weapons.
The World
One of the strongest aspects of Dying Light would be the open world city you are placed in, called Harran. Harran is large and full of buildings to climb, perfect for the parkour you will be using to get around. Since it is an open world game, you are free to roam around, finding loot that can be used to create new weapons, and discovering side quests that can be received from the survivors that populate the city. The great thing about these side quests is that they can become their own adventures, developing their own small storyline that could see a typical rescue mission turn into a trap. Source
Day and Night
There are two modes to Dying Light, the day and the night. While the day is filled with zombies that you will enjoy slicing through, the night offers a very different experience. When night falls it unleashes more terrifying zombies, like the Volatiles, a type of enemy that is hard to take down and will cause massive damage if it catches you. It is because of enemies like Volatiles that night focuses on stealth rather than fighting, and if stealth fails you could find yourself sprinting to the nearest safe zone. However while it may be tempting to stay in a safe zone during the night to avoid the more dangerous enemies, the night does give you an incentive to head out and brave the terror: the amount of XP you earn is doubled. This can allow for quicker leveling up and gives you a reason to go out during the night.
Guns
An interesting thing about Dying Light is that even though it does include guns later, it does not make them the weapon that could change the game. The guns have a slow rate of fire and the noise they make attracts more zombies, making them more a weapon to used only when you have to instead of the first choice.
Co-op
While some people may prefer to play alone, many people like to play games with their friends. Dying Light offers a co-op mode to allow for this and allows for up to three friends to join you in your game.
Dying Light is vast open world game with a long campaign and plenty of side quests and discovering of new weapons to keep you busy for time to come.
