Project Bluestreak video looks the same as the old one, but isn't

Cliff Bleszinski, aka Cliffy B, aka The Cliff Man, aka The Blesmeister, is unveiling Project Bluestreak tomorrow .

. The free-to-play shooter has been in development for a while now, and a pre-alpha teaser released in March has, for a long time, been our only glimpse of the title.

That's changed now, but not dramatically: Boss Key has released footage very similar (basically identical) to the pre-alpha teaser, with one subtle difference. Can you see it?

What's the difference? Well, skip to 0:32 in each video and take note of the skybox in the background. You'll notice that there's a tonne of debris floating upwards. It's not a very interesting change in and of itself, but it may have something to do with "The Shattering" – an oft-referenced phenomenon on the game's teaser website.

Whatever the case, it seems to indicate that something apocalyptic has happened. We'll find out for sure tomorrow, I bet.
