If you were around the ‘net in the early 2000s, you might remember a browser game that ran on the LEGO website called The Nightfall Incident - now regarded as a cult classic. Nightfall Hacker is a full-featured homage with additional programs, way more levels, and the inclusion of a level editor (watch the trailer for a full breakdown).
In Nightfall Hacker, you're a freelance hacker - someone who lives and dies by code. Making money is easy: All you need to do is to accept jobs, deliver the goods, and get paid. Win enough new clients, and the world is yours - with the upgraded programs that go along with it.
