How to change your skinEdit
To change your skin, simply make an account, and select the "Edit Profile" at the header of the site. There you will find all of the skins and their avatars to choose from. Remember to click "Update Profile" after selecting to save your choice.
If you try to change your skin using "Inspect Element" browser option, when you will update your profile it will say "Deathmatch Model hacking attempt detected" above "Your account updated successfully" and reset your skin to the default Marine.
