I was poking around in the Alpha Team files tonight, and found several things I wasn't expecting.
CATEGORYIMAGES.TXT:
0 lego
41 group1
42 group2
43 group3
44 group4
45 group5
46 group6
35 ogel
1 global
19 trop
36 sub
37 sea
38 polar
39 mtn
40 moon
Notice the last six entries there? They're the zones in the game, in the order they're played through... Except the final game only has the first four listed there. This file lists two zones that didn't make the final cut: Mountain and Moon. Seeing as the other four zones are listed in the order they're played through, I think it's safe to say that the Mountain zone would have come after the Polar (Arctic) zone, and the Moon zone would have been the final set of levels in the game.
But wait, there's more.
CATEGORYUNITS.TXT
"Cyberia"? What the heck is that? Perhaps a leftover from LEGO Logic? There does seem to be some sort of portal in the TILT HQ, so perhaps that's what Cyberia is?
And there's a listing for a "Neandert" enemy, which is just a few letters away from "Neanderthal"... Who wants to bet it's the big blue primitive looking creature from LEGO Logic?
There's also sections for the scrapped Mountain and Moon zones... Which are completely empty.
Also, notice that the section listing all the Alpha Team members is titled "T.I.L.T.".
There's an asteroid of all things listed in the "LEGO UNITS" section, and a texture named "ASTEROID 2.TGA":
At first I thought that perhaps the asteroids appear in the training... space place... But I just checked, and there are none. Perhaps they were for the Moon zone or something?
Another odd thing, Dash and Radia's texture names are pretty weird. Dash's textures are LASERBODY.TGA, LASERHEAD.TGA, etc, while Radia's textures are PIPBODY.TGA, PIPHEAD.TGA, etc. All the other team members are identified by specialty rather than name, so why are Dash's textures identifying him as the lasers expert, and what the heck does PIP mean?
Finally, there's a bunch of textures that appear to be for a debug GUI or something - buttons for each listing in CATEGORYIMAGES.txt, more finalized looking buttons for each zone (including the Moon zone, but not the Mountain zone, oddly), etc. There's quite a few so I won't be uploading them, if you want to see them for yourself they're in Etc.pac.
I'll keep digging around and will post anything else I find.
