An emergency relief team will be dispatched to your location. *Static* Estimated arrival time: 9...9...9...9...9 hours". The wait time is a possible reference to Portal 2, whereas announcer says to Chell: "You have been in suspension for nine...nine...nine...nine...nine..."

The Propulsion Cannon and Repulsion Cannon could also be references to two of the gels used in the game Portal 2. There are four gels in the game, two of which are named Propulsion Gel and Repulsion Gel.
