James Bond 007: NightFire

once you've installed the q-worn on the "red" computer, you need to find a "green" computer that will automatically give you a keycode when you step near it and press A. Then go to the door that is locked with a keypad next to it (it's near the moving red laser beam) and press A to bring up the keypad. Now enter the code it shows on the screen (the one you previously got). Shoot the guard through the door with dart and head through the door on the opposite side. Continue through the hallways shotting guards with darts and avoiding red beams until you get to a metal door with a keypad next to it. Switch through your gadgets to the "decryptor" and aim it at the keypad. Then hold R for it to figure out the code. You will now enter the "security center".
