http://callofduty.wikia.com/wiki/MDT it is a thing from the zombies universe. its is a teleporter, created by richtoffen and maxis, used for interdimansional and time travel. The idea for RWBY is that the MDT malfunctions and breaks down(a common problem with the machine) after richtoffen experiments with a remote control for the teleporter, allowing them to return to any teleporter they please, and though it works, the machine has an error, causing it to launch them into a random dimension, leaving the four stranded in Remnant. Scattered around are supplies and their wepaons(most commonly used ones in cinematics), but they had changed, become multi functional, and no ammunition, instead having dust inside it. After an encounter with the Grimm, they decide to enter the nearby Vale, which is overrun. After days of scavenging, they decide to try and fit in with the world, changing their last names to match the trend, forming their team, and starting their mercenary group. Their final goal is to collect and repair the MDT, which is now hidden in Beacons Basement(its behind the life support systems), and try to get back home. WIth the Grimm acting as their new enemy, they face off against them and other forces in their fight for survival.
