These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Anti-Climax Boss: Subverted - Lennox's death happens so suddenly at the end of the game that it looks practically like an offscreen death. This is deliberate, because Lennox isn't really dead - the whole game was just a cover so that the US could go after the real Lennox in secret, using the events of the game as cover.
Rated M for Money: Zig zagged - the violence in the game is as intense as that of any other FPS, there's a considerable amount of swearing, the protagonist is shown committing an act of torture and constantly smoking, but, bizarrely, there's no blood or gore in the game.
