This is a complete playthrough of level 12 - The Grand Cathedral -- on Serious Mode difficulty, triggering all the hidden secrets, without saving or dying.

Highlights:
0:18: The Corridor of Death, Wave 1 - Mercenaries and harpies, with a few Curcubitos and Zumb'uls.
2:44: Wave 2 - A biomech, Zumb'uls and a lot of Kleers.
5:18: Wave 3 - Major and minor biomechs, Gnaars, mercenaries
6:45: Wave 4 - Major biomechs, Curcubitos, cannons, werebulls
8:44: Wave 5 - Major biomechs, mercenaries, werebulls, and Fiendian reptiloids which hide around the corner (see Wave 6)
9:42: Teleport to secret pumpkin field. Cannons and mini Curcubitos.
12:04: Wave 6 - Fiendian reptiloids left over from last wave. Kleer skeletons, Curcubitos, werebulls.
14:59: Wave 7 - Kleers, Zumb'uls, reptiloids and Fiendian reptiloids, kamikazes, major biomechs. Enemies start spawning in behind you in this one.
16:46: Wave 8 - Major biomechs, Curcubitos, Zumb'uls, werebulls, and lots and lots and lots of Kleers (many of them spawning behind you). This wave will push you almost all the way back to the beginning of the level.
22:02: Final corridor wave - lava golems, Fiendian reptiloids, harpies, major biomechs, cannons.
24:36: Teleport to Ugh-Zan embryo museum, 2 Highlander reptiloids
26:22: The incredibly annoying and difficult courtyard with bouncy pads. I lost track of the number of times I died at this part of the level. Major and minor biomechs, cannons, marsh-hoppers, Kleers, harpies that drop kamikazes, reptiloids.
32:44: Triggering the final battle in the wide open field. The ammo, health, armor, Serious Speed and Serious Damage in the central area do respawn, which is a good thing because it's needed. This battle is the most intense fight in the game. Every enemy in the game will come at you in wave after wave. Nothing you haven't seen before, but it just doesn't let up and keeps ramping up and up in intensity. Once the meteor storms start, you can't even venture too far into the field lest you get hit and take heavy damage. Very, very intense battle.
40:40: I made a series of screwups (meteor hit, Kleer hit, rocket hit, run into Kamikaze) which took me down to 13 health, the lowest it had been in the entire game.
44:32: The last straggler is killed. Refilling health, armor, ammo before heading across the field.
45:38: Entering the last courtyard for the final mega-boss battle against Mordekai the Summoner. This battle killed me several times before I got it right, and let me tell you, dying at THIS stage of the level is enough to make you want to pitch the computer out the window.
53:50: Mordekai falls! Final cutscenes with Sam "confessing" to Mental in the Grand Cathedral before taking off in the Cathedral Spaceship. End credits, applause.

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.
