Part I: The American Dream:

Chapter Two: Live from the Crime Scene:
You can shoot the wailing siren in the central vault area and Max will thank you.

Chapter Three: Playing it Bogart:
If you walk past Rico Muerte's room to the end of the hall, you can shoot away a boarded-up door. From this room you can walk across the ledge and shoot away a boarded up window to find a dead body with a stake in it lying next to the word "Buff" in blood (as in "Buffy the Vampire Slayer"), as well as some other goodies.

Chapter Six: Fear That Gives Men Wings:
As you ride the elevator up from Luigi's Laundry, shooting the speaker playing sappy elevator music will bring another "Thank you" from Max. Shortly thereafter, as you leave out the window from the room sporting the thug in the bathroom and the TV news report, walk to the left and there will be a window you can jump through to a room with two Soldier of Fortune 2 posters and a stash of shotguns. If you didn't destroy the elevator speaker earlier, you should be able to hear the music from within this room.

Chapter Seven: Police Brutality:
When Gognitti reaches the locked door, there is a satellite dish behind you on the ledge. If you jump from this corner to the ledge across the alley, you can drop down into the fenced area and open a door to a room with a nice assortment of ammo and a poster proclaiming "Dopefish Lives!" Dopefish is quite possibly the most prolific character in Easter Egg history.

Chapter Seven: Police Brutality
At the basketball court, there is a Beretta stuck in the net. Also, if you wait by the fence, an SUV wil drive by. If you shoot it, it will crash and the driver will get out to shoot at you.

Chapter Eight: Ragna Rock:
When you reach the inner stage area, you can "use" the drum kit and microphone and step on the guitar for some interesting effects and dialogue.

Part II: A Cold Day In Hell:

Chapter Five: Angel of Death:
When you reach the grand piano, you can "use" it and Max will play the title theme. You can get a different effect by shooting out the lid support and trying again.

Part IV: A Bit Closer To Heaven:

Chapter Four: Backstabbing Bastard:
At the entrance ramp to the car park (from where you start), there is a stack of barrels and an air conditioning unit that you can jump on to reach the roof of the garage. Shoot the off-color panel of the shed there and it will fall away. Inside, you can jump on a grate to fall into a room with the grafitti "R Thanks", a radio you can "use" to hear audio from the production team, and a sniper rifle with ammo.

Chapter Five: In the Land of the Blind:
In the small room after Woten's office (where you find the Aesir building plans), there is a small picture that you can shoot off the wall, revealing a button. Pressing it will raise the couch on the other side of the room, revealing a staircase down to a "private area". In it there is a big screen TV you can use to play a 3DRealms-themed parody of Star Trek. In the adjoining room there is a bed with chains next to a closet full of bondage gear.
