First: I visit this community only sometimes, so I have no overview, what is new, or something has changed. Second: I tried to find topics about this, I found something, but lot of them are by old date.
I started play Descent Freespace sometimes in autumn 1998 year, when this game was new. Orion was massive ships, but something was wrong - too less turrets. 16 turrets is too little for that big ship (15 turrets for PVD Typhoon ditto). In FS2 nothing changed, Orion was little obsolete destroyer and was replaced by Hecate class, so for GTVA technicians "there was not reason for more turrets".
But this ship is still very popular and in age of AAA turrets, flak guns, beam turrets and other laser turrets is 16 turrets very little. In FS2 this was extreme: on left side were only three turrets, which were armed by beams against big ships, so on left side Orion was totally unprotected from fighters and bombers! So Orion needs more turrets. I found
TrashMan version, but file gives 404 error.
FS2 Open gives lot of possibilities, so if nobody so far did not make Orion with more turrets, PLEASE do it and make it as default Orion for SCP. Orion with about 25-30 turrets would be great war ship in FreeSpace Universe.
