Lt Carmack? <spoiler>

[Foodles]

Ok so I've done all the missions on the final tier and it says report to Lt Carmack but I cant find him, theres a guy with a clipboard standing near the power up shop but nothing happens when I go near him, where do I go?

[Jimmy]

That is Carmack. Not sure why nothing's happening.

To progress, however...

---

Go into the lounge to the right of where Carmack now is and talk to the scientist guy looking out of the window.

Hang on a minute, isn't he the marine who briefs you?

On the last section of INTERMAP/MAP99, Walk off the middle of the U shape, he's somewhere down there...
