Great Mine: "Get in that hole!"
I started a new game (on "casual" mode) and played it to the first Maul Griever battle in the Great Mine with Duke and Armstrong. Normally, when the drill breaks through, I just jump in the hole, but I've always wondered what the game would do if I didn't jump. So this time I didn't and kept firing. The number of Grievers slowed but they kept coming and Duke started yelling stuff like: "Get in that hole!" "Hurry, they're still coming!" LOLOL It was hilarious!!
