An HOUR!

Being unemployed-- er, I mean, between jobs-- it's time to hold off on buying new games and go through my shelf for old games I never finished. Last night I completed Serious Sam: Next Encounter, a straightforward and decently fun first-person shooter which featured a final boss fight that took me AN HOUR. This won't be interesting to read, but: the last boss of the game is a large flying humanoid with about a hundred pieces of armor that must be shot off individually. Then, and only then, do you expose the tiny weak spot on the head, which requires precise aim to hit and is only exposed for about six seconds. (An internet FAQ suggested that I use the sniper rifle, which is clearly nonsense because he flies all over the darn place and out of your scope while you're zooming in and there is NO WAY to snipe that miniscule spot on his head. I tried.) If you have a steady hand and use a powerful weapon, you can maybe knock off one twelfth of his health. Then all of the armor gets replaced and you slowly blast it all off all over again. There's plenty of respawning health and armor lying around, so it's not even a challenge; it's more of an endurance test. I'm telling you this in case you, the reader, happen to be a lead game designer, so that you DO NOT PUT SUCH A THING IN YOUR GAME.
