Shadow Complex for free
This is kind of naughty, and I feel a little bad for the developers, but here it is.

Essentially, keep hammering the start button as soon as the big spider robot starts exploding, and as soon as it will let you, select "load last save".
This glitch allows you to play the full game of Shadow Complex just from the Demo. It essentially skips the point where the demo ends, and lets you carry on for the rest of the game. I've tested it myself, and can confirm it works.
I assume you'll need to play the whole game in one setting, since I don't think you'll be able to resume you game from the demo, but it's not too long a game anyway.
