It seems the developers of Shadow Complex overlooked quite an important default when compiling the program. Many gamers have discovered that by simply pressing the ‘Start Button’ at the end of the Shadow Complex game trial allows them to play through every part of the game on demo mode.SavyGamer who made the discovery reported on his blog...
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.
I think it’s probably for the best if you treat it like an extended demo. If you play beyond the demo, and enjoy it, then buy it. You’ll probably want to replay it anyway.
EPIC, the game publishers, have removed the video from YouTube!
