The Aperture National Bank Heist

The Aperture National Bank isn't known to be the most polite bank, but it is known to be the richest one. As you and your team got your hands on the plans for the bank, you now want to get the most expensive money cube out of the bank today. Sadly your fellow team members all want to have the cube for themselves. You may not have the plans, but you are the first one to arrive in the bank. The only thing you have to do now is find your way into the Second Level of the bank on your own.

More Levels will follow...
