Finally got around to playing (or replaying, depending on how you look at it) this the other day.
The little architectural touches you added are very nice, does a lot to add to the atmosphere of the maps. Didn't notice any new skyboxes though, just the same ones that were in the original Vavoom release (I must be blind, heh).
Only thing that bothered me a bit was that you
kept those friggin polyobjects in MAP06; you think 8-10FPS is low, they slow the game down to about 1FPS (seriously) for me. <!-- s:o --><img src="{SMILIES_PATH}/icon_surprised.gif" alt=":o" title="Surprised" /><!-- s:o -->
Oh well, at least it didn't crash on me after a while like it did in the original Silent Steel. <!-- s:lol: --><img src="{SMILIES_PATH}/icon_lol.gif" alt=":lol:" title="Laughing" /><!-- s:lol: --> (not sure if the new map changes or the new version of Vavoom fixed that).
Anyway, other than that one thing, nice maps. <!-- s:D --><img src="{SMILIES_PATH}/icon_biggrin.gif" alt=":D" title="Very Happy" /><!-- s:D -->
