Highlights: 5:50: Hidden bigheads and Secret Hall of Fame (damn, Croteam is weird) 8:27: Valley dead-end battle against kleers 11:16: Serious Speed courtyard fight 16:00: Secret Mental's room 17:56: Four-sided kleer skeleton fight 25:07: Underwater tunnel to secret cave 26:35: Final wave of enemies on the way to exit Notes on the video: I originally played and recorded these demos back in 2002, just after Serious Sam: The Second Encounter was released, following up on the demos I had recorded of a Serious Mode run-through of First Encounter. In that run I hadn't triggered all the secrets, so in this run-through I triggered all the secrets as well. The demos were originally uploaded to (and are still hosted on) the Serious Sam community site http://www.seriouszone.com/ , but I'm now uploading these to YouTube because the original demo files required 1) that you actually have the game to play them, and 2) that you have the out-of-the-box, unpatched version of the game as well. If you had upgraded to the patched version of the game, several of the demos were unplayable past a certain point, so here you can see the levels played from start to finish as I originally recorded them. Since the game has been remade in HD, almost no one plays the original Classic version of the game anymore, but I wanted these not to be lost to time.
