like mike I normally don't check out anything without pics, mainly due to always just seeing another compiled default content project with a small twist. but glad i did, this was really good graphically, fast load and even some hdr like effect when inside the hanger/cavern (though the effect caused some lag there on my 450 gts (1680x1050) so id say the effect could use some tweeking though as these effects don't usually slow my system down as much as in this demo if at all, but i did get 60fps through out with 1440x900 resolution).
also the right side of the main door can be walked through allowing you to walk out side, not sure if this is by design.
loved the physx based doors, big fan of that
.
maybe check your randomised spawning of the crates as they sometimes spawned inside eachother and repel eachother up into the sky on creation.
anyway just some quick feedback from a few plays through, good to see some effort going into a rad project!
