In the Rig map there is a circular platform near the Catwalk, Pit and Drill areas that can be ground pounded. When this is done, two Power Cores in the Back Rail and Yellow Corner areas will activate which can also be destroyed. If the player does that then an Easter Egg will trigger where, off in the horizon, a giant alien sandworm can be seen revealing itself while it devours a large facility, in reference to a similar scene from David Lynch's 1984 film adaptation of Frank Herbert's sci-fi novel "Dune".

On the multiplayer map Riptide, a Meeseeks Box from the TV show Rick and Morty can be found in a canister.
