As someone who is a huge fan of horror games, Dying Light walks a well balanced line bordering on action adventure and zombie slaying goodness.
During the day you are playing a game of 'the street is lava,' parkouring through the rooftops only making a quick dash onto the street to scavenge supplies or make a more direct path to your destination while avoiding zombies. Any interaction results in a fluid combat experience that only escalates as your character levels up.
Night brings many more challenges as your visibility is sharply reduced and the abundance and difficulty of zombies exponentially increased. It is advised to avoid these scenarios until you are between levels 7-10.
Believe me on this one guys... as much as a badass as you may think you are, these zombies will rip you to shreds unless you are leveled up and experienced in the control system!
Early on, focus on leveling up your agility class as running and avoiding zombie hordes is your main tool of survival.
Overall the gameplay is fun, fast and fluid. Crafting is nice but can get repetitive with the same items being scattered all over the world.The game is not too well optimized for PC at launch (mainly for AMD users) but turning down your draw distance can help combat some of those FPS jumps.
If you have an Nvidia setup (like myself) you should be well off for a smoother gaming experience.
I'll also add that I have been playing this mainly co-op so far and that if you were like me and mistaken in thinking that this game was going to play exactly like Dead Island then you could not be further from the truth... CO-OP IS AWESOME!!
Sometimes the item scavenging can seem repetitive but night time hunts hold high yield loot. Early levels of your skill sometimes make simple side mission runs a long daunting task but once you learn to adapt to your surroundings you can escape many situations.
Overall this is a great game and a must for any horror/zombie fan or even a game fan!
