Graphics are great, both good looking and doesn't need a powerful device to play on. Story is nice, missions have a meaning, it isn't based on just killing zombies. Having a variety of weapons is very enjoyable. Bullet system and economy in game is balanced, it makes you feel like you should not waste your supplies, which makes this game fit it's post apocalyptic story and ambiance. Best quality game I have played on mobile in 5-7 years, Very well done.
