It was awesome, but the funny thing was - if you go back and watch the shaky-cam footage on YouTube, there's this bit where we were meant to reveal this big number, like USD 50 billion of PlayStation revenue or something, and there was this big brick wall in front of it that was meant to be blown away... but because the game had been sitting there for two hours, or whatever, the explosives had rolled down a hill and detonated in a later section of the level.
So when I got to that bit, not only had the USD 50 billion been blown away - so that was a bit of an anti-climax, although nobody noticed apart from me - I was absolutely white with fear, because I knew a bunch of bombs had just rolled down to the next bit of the demo, which was all of the game titles popping up.
So I had no idea, as I went down the hill, if Resistance would pop up with a chunk out of it. Luckily, if you look at it, there's just all this blast damage all over that section, and charred stuff lying around. That was a dark moment. Apparently the whole team was watching on the live feed and screaming "Alex! You've f*cked the level!" But it wasn't me, the bombs just blew up while I was on-stage...
