This has been posted in this thread before and isn't a secret in any way, but with 154 pages I can see how it would be missed.
Besides myself the Alien US team is -
Kelly Mazurowski - Animator
Joe Schober - Programmer
Brian Dominy - Programmer
David Thiel - Sound
Kelly is a professional animator and pinball player, you've probably seen some of his work if you've played Metallica, Star Trek, or Mustang as he contributed some dots to those games. Otherwise his commercial work has been outside of pinball. He's a good friend of mine down in SoCal with me, so we work together in person on ideas sometimes.
Joe and Brian share programming duties, and are both tournament players. Joe is more focused on the rules, and Brian more on the low level stuff, but they work together as needed, so whatever needs to be done is handled one way or another.
David Thiel I would think needs no introduction, he's been a joy to work with. Really the whole US team is awesome, love working with all of them, and we collaborate really well.
Brian wrote a simulator that allows us to test the rules, hear the sounds, see the animations, all that good stuff. But since we're not in Wales obviously we haven't had hands on time with the game yet. So that's what I mean by after we've had that time we'll start working on polishing things up.
And it's polish work, the heaving lifting is done. This game already has more complete code right now than some shipping commercial games have had for instance. Nothing I'm talking about from our side would delay production. But we're going to see the game for the first time as everyone else, so I'm just saying if there are any things that need some attention to bring it up to our standards don't worry, we're going to take care of it.
