Two competitive twin sisters accept an offer to play "the ultimate lazer tag". What they find is that they are not just playing for fun, they are playing for an intergalactic audience...
This episode was pretty good until the "Betatron" bit. That was just silly. This reminds me a bit of "The Tale of the Zombie Dice," in that the kids are being used as a form of entertainment to alien life (well, in "Zombie Dice," the buyers weren't exactly aliens). It was also very nebulous about the purpose of the Betatrons. The man said his people weren't agile...so, they needed the Betatrons to play for them. So, why make so many copies? Why make copies at all? It was just so silly and unclear and frustrating.
