I suspect you need to enter something on the official website. If you scroll, there is a box you can enter a code into.
Entering random words gives you the message "Incorrect Password. Please locate cipher".
Entering the characters in the video gives you "Incorrect password and field. Please decode cipher instructions and use elsewhere." and a blue box instead of a red one.
On the right, there is a little arrow. Clicking it will bring you to another box that gives the same results. Clicking it again will bring you to yet another box, except this time the message is "Incorrect password. Please decode cipher instructions."
To me, this seems to mean that we're supposed to get instructions on how to use this string somewhere. Either by decoding the string itself, from a future or past video, from some other material, or this is a long con and it will be from the game itself.
Thanks for the tip! I looked this up online. It was pretty helpful. The problem I seem to have w/ the Batmobile is that the controls are quite delicate, so aiming, especially at the helicopter, is, as you'd mentioned, tedious.
Edit: The other part of this that I now realize makes this even more difficult is the controls. I was able to get through ground units a bit easier, but once I started w/ the helicopter, the controls were inverted. I tried changing them in the options, but switched all the battle controls, not just movement controls. It's tough getting used to remembering that up is down and down is up.
Haha, man I knew people would call out Batman Arkham Knight, my good friend is really keen on it and he busted me for it too! I'm Not a fan of the series (because I for some reason don't enjoy those sorts of action games as much now a days, and haven't been a big fan of Batman in general for a while.) That's why its not on here.

I checked out the actual site and it doesn't look to be available in your country. I might check back at the link below to see if Spain pops up between now and the release. You might even want to start a thread about it and maybe a retailer might pick it up.
