In Chapter 2: "Damn! It's Late...", after walking off the set, you will see an actor yelling at someone. He says things like "Do you want me to trash your mics? DO YOU?" and "You're a nice guy, you really are but you're a f**king amateur". This is a reference to when Christian Bale freaked out on the set of Terminator: Salvation.

In "The Hive" chapter, after you tickle the first door, turn to your left, and walk forward. Crouch to get under the bridge, and you will see a dead EDF Soldier with Isaac Clarke's signature engineer helmet.

In the "Duke Nukem's Titty City" chapter, go to the game room at the back of the club, and play a game of air hockey. Instead of focusing on scoring, try defending your goal as good as possible. The rest will happen by accident since the opponent is very weak.

Pinball games are located in different locations throughout the game. The first pinball game can be found in "The Duke Cave" chapter. While playing the pinball game, to speed things up, you should get at least a x2 multiplier without wasting a ball. Hold the top left flipper, and bring the ball up there. Quickly release the flipper, and let it hit the three panels. If the ball is getting too far on the right side, you can tilt the table to the left by using the Left Analog-stick. Keep repeating this method. Do not use the tilt ability more than once every five seconds. If you use it too often, you will lose control over the flippers.

The first helmet is at the very beginning of the "Vegas In Ruin" chapter in the back of a vehicle. The second helmet is at the beginning of "The Hive" chapter. Turn left after going through the first alien hole to find it. The third helmet is found in the "Blowin' The Dam" chapter. After planting the first bomb and fighting two octopuses, swim to some debris to your left to find it and get the "Bucket Head" trophy.

In Part 2 of "The Forkstop" chapter, you will reach a large area where you need to turn the power on. After killing some waves of enemies, use the forklift, and climb the wall to your right. Grab the heart barrel, and go to the other side. Place the barrel on the blue heart drawing on the ground to open the secret room and get the "Companion Barrel" trophy.

There are 28 Ego Awards. There are a couple extra rewards that are gained automatically by playing through the story. If you get all Ego Awards during your first playthrough, you will get the "I Am All That Is Man" trophy in the "Blowin' The Dam" chapter.

In "The Shrunk Machine" chapter, near the beginning, after entering the first large room, straight ahead across the room are some double doors. There is a calendar on the wall behind the double doors. Look at all pages to get the "I Need A Date" trophy. There is another calendar in Part 2 of "The Forkstop" chapter on the wall in one of the rooms.
