Mini-Harsuit in training mode[ | ]
When you come to the default weapon rack next to the exit door, crouch facing the door, and under the weapon rack you'll see a mini Hardsuit. Shoot it, and it comes out on the other side.
Training Holo-Dummy Bar Codes[ | ]
In Training mode, a bar code can be seen on the holographic training dummies. It was revealed that the bar code reads "Be sure to drink your Blacklight Retribution." This is a reference to a famous scene from the movie "A Christmas Story," when a code is cracked and translated to "Be sure to drink your Ovaltine."
Secret room in training mode[ | ]
There's a room that contains premade guns that you can pick up and use. It's in the same room as the large legged-tank. To access it you'll need to stand on the final door before it raises after the tutorial is finished then find your way there. This involves getting on the platform and jumping down on top of the walls.
Brandon's Box[ | ]
In Containment there is a box labelled "Blacklight Comics" and on the back of this box is a taped label named"Brandon's Box." This is a reference to a developer who goes by the screen-name "ZombieBrandon," who used to camp behind a specific box in Retribution's prequel, Tango Down, to the point that it became known within the office to be called, "Brandon's Box".
