This attached zip has the remaining missing icons. There are some new Harvester skulls (taken from a Public Domain skull, exactly
this one) and icons for the rest of the TA items. (Invulnerability, Portal, -unused on TA, maybe it was an item which couldn't made on the MP- & the true names of Kamikaze & NG/CG/PL weapon & ammo stuff)
EDIT: Two screenies attached, one with the new skulls, and the other shows the Invul with cg_simpleitems = 1.
