At the point when Nima and Miles first come across the fences and notice that they are electrified you can click on the sign, the first two clicks Nima say "Ten thousand volts? why so much?"/something in spanish, but on the third or forth she says "1.21 Gigawatts? Why so much?".
I though that was a pretty funny Back to the Future reference, also clicking the sign after that makes the camera zoom up close on the hand which struck me as goofy too lol
just though I'd share that, anyone else notice any Easter eggs?
