Shout Out / Heart of Evil

• The whole mod is basically a videogame based on Apocalypse Now and Heart of Darkness, so there is a plethora of references to them.
  • "Ride of the Valkyries" play as Percy flies through the helicopter to the mission through explosions and gunfire.
  • " The horror... The horror..."
• "Me so horny. Me love you long time."
  • A Drill Sergeant Nasty is heard shouting at his recruits at the beginning of the game.
• A portion of the game is spent in Raccoon Military Base, where you have to find three different colored crystals and colored keys to progress.
• "Look over there! A three-headed monkey!"
• "Damn, I'm good."
• "When there's no more room in hell, the dead will walk the earth", written on a wall by the man who had taken the same mission as Percy earlier.
• "OH GOD! THEY KILLED KENNY! YOU BASTARDS!"
• From the briefing in the Napalm Edition: "Stop staring at my secretary, Freeman! This isn't a high-end videogame where your sidekick is some hot chick you can ogle with a set of binoculars!"
  • Likewise, you can play an arcade game of Half-Life 2.
• "But by myself, I can run like Benny Hill."
• "You wanna dance? This is called Rickrolling, bitch!"
• "You have picked up a chainsaw! Go find some meat!" Complete with a remix of At Doom's Gate.
• "Di di mau!"
