All Gameclub PH games are completely free to download and free to play. All you have to do is create a Gameclub account, which is quick and easy, and also totally free. Please check on the "I want to play Crossfire! How do I sign up?" article to know more about account registration.
In every Gameclub PH games title are item shops from which you can purchase cool items that customize and expand your experience of that game. These items include new clothing and accessories for your character, in addition to functional items that extend your character’s abilities, or new awesome and powerful guns.
These items are, and always will be, entirely optional. You will never be required to buy anything on Gameclub unless you want to.
