please need help I decoded the cube with all the right number dont know what to do now cant find bomb or other part of mission

After decoding the cube you need to gather some intel. If you're trying to complete all the objectives you can check out a list of all the fingerprint and profile locations HERE. You have in your tool/weapon inventory a fingerprint scanner and you need to find a fingerprint(handprint actually) to be able to gain access to the security area that you need to go to. If you look at your OPSAT under equipment, you'll find it listed and more info on it.

Primarily you get a fingerprint scan and use it to access the high security area where there is a computer that is monitoring the bomb location. Once you access it you will have completed that objective and must head back to where you decode the cube and wait for time to run out. At that point Emile will come check out your work and then you will have the 'choice' objective come up which will be the end of the mission.

To find the locations of various items, use the 3D map in your OPSAT. Using it can be a valuable aid in navigating the HQ.
