--- Comment #1 from Shomy shomari.sharpe@gmail.com --- from observations running the game on my Windows 7 partition (boot) once the game loads the following files are seen in the task manager (process list) * CombatArms.US.aes * NexonGuard.aes
A Logo displaying "NEXON GAME SECURITY" should appear at the bottom right of the screen just before the game screen initializes.
