Press play on this video. For around 40 seconds you may think it's actually the debut trailer for upcoming blockbuster Black Ops II. Then you get to 41 seconds and, sadly, you realise that as wonderful as this is, it is not the debut trailer for Black Ops II.
For reference, the actual trailer goes live in 20 minutes time (8pm Eastern). You'll be able to watch it right here on Kotaku.
UPDATE - You can catch the actual debut trailer right here.
