Awesome / Command & Conquer: Renegade

• The Ion Cannon. From the moment you activate it a light rain starts up out of nowhere as the atmosphere ionizes, columns of light swirl together over the target, and... BOOM, everyone dies.
• A cutscene begins with a Nod commander ordering the immolation of several civilians. Needless to say this provokes a very pissed off, "REAL TOUGH GUY!?" from Havoc, who promptly snipes said commander in between the eyes.
• Of course, this being a game based on playing as one of the series' infamous Commandos, there are tons of lines like that. Paraphrased example:
  Prisoner: You're going up against the whole crew by yourself?
  Havoc: Don't seem fair, does it? Maybe I'll shoot left-handed.
• Earlier in the same level, two Nod soldiers are checking out the submarine in the ship's hold.
  Nod Soldier 1: It's one of those new subs!
  Nod Soldier 2: Impressive! Are they armed?
  Havoc: (hops out out of the sub and shoots both of them in an instant with his pistol) This one is!
• One of the themes is based around Havoc's catchphrase "I got a present for ya".
