Probably one of the best Open world Zombie game out there. The BGM, the SFX, the Characters played a great role throughout the entire game. The ultra realistic graphics blew my mind totally and made me bound to think that is this a video game or a full length feature film on Zombie outbreak. The Storyline is very strong and intense. Trust me, playing this game will increase your IQ level, sharpness, stealth strategy in any game greatly. The night time and the day time in the game are very different. For example at night time zombies are faster and more aggressive than in day time especially when you play at survival or survival 2 difficulty. Jeff Ross the director of the game amd his entire crew did a great job. Really man ! Hats off to them for coming up with such a minimalist yet great idea of an open world survival horror game.
