Item description:

I recommend you complete the game atleast once to unlock achievements in the legit order.
First load up a level and in the inventory seen a few achievements will pop then buy a
weapon and do a upgrade on it and then another will pop now put some rotten eggs in your
inventory and ready up, now a few more should pop if not then will when you kill 1 zombie
also use the rotten eggs to kill a zombie to unlock another 1, and try shooting a BSAA
emblem to unlock the emblem achievement. Now when you finish the level you should get
professional/veteran achievements. Ok now go into bonus features and buy anything and you'll
get the clothes/figurine achievements.
