Hello, and welcome to the Insurgency: Sandstorm Pre-Order Beta 2.
We're really happy that you're joining us here, and would like to let you know of some issues that we're currently aware of, in this build of the game.
Point 4 of many others ----> - Character Customization: For any players that were present in any Alpha or previous Beta please delete your profile.sav in the below location: C:\Users\UserName\AppData\Local\Insurgency\Saved\SaveGames\Profile .Otherwise you may experience character body parts disappearing or showing two cosmetic options at once.
