I have pink gun and accessories textures!

If you are having pink textures show up within your game it is usually a indication that the hardware in your device is creating some conflicts. You can try lowering the Graphics by going from main menu -> Options -> Audio and GFX tab and then try adjusting it to Medium and Low.

If you are still experiencing some pink textures on your accessories you can also try putting a camo on the selected parts as some users have said this has worked for them.
