It seems like attack speed item is not working correctly. The first attack speed item, which is level 1, is reflected to my status view by increasing the attack speed value, but the later ones like attack speed level 2 and 3 won't increase my attack speed at all at the status screen. and also I feel like the actual attack speed don't get any faster.
In addition, is there attack speed limit in the game? I want to shoot a gun like crazy :)
By the way, I really enjoy this game and love the way to boost the ability of my character to sweep out zombies! This is legit!
