Halo 3/YMMV

• Anticlimax Boss: 343 Guilty Spark.
• Best Boss Ever: The dual Scarab battle on The Covenant. Probably the coolest battle in the series.
• Best Level Ever: Uh, can I nominate the entire second half of the game for this?
  • No. That would include Cortana.
  • Then "The Covenant", where Master Chief and a small army takes out two Scarabs. And there are not cutscenes for that, you have to pilot something onto the backs of those things and blow them up yourself.
  • The Storm is the best level in the first half.
• Complete Monster: Truth is far beyond redemption by this game.
• Memetic Badass: In Halo 3 multiplayer, the Cone. In the first days of release of Halo 3, a player shot the energy barrels of the level, and was subsequently killed by a flying traffic cone. SPARTAN-II are afraid to tread near them.
• Moral Event Horizon: Spark crosses it when he kills Johnson.
