Komen zero002

what does the achievement called one of us mean?,how could i do it? this game good but its quite short and easy.The graphic is pretty good but there is something that is not good.the upgrade is too little and compare to the zombies that when you have all of upgrade you will be a demon to them.even when i have 1/6 health point when i am going to fight the final boss i still win without losing half of rest of my health.i think this game should get 3.5 stars and you should get more upgrade about this game if there will be ep 2

does any one know how to swap the profile on this game from another website.I played this on FWG and i really like it and i want to swap my profile to this page to get more feature.Please help me and thanks
