I will be offering the PCs a range 9 weapon that fits into the slot occupied by the missile launcher later in the game, but...  you'll have to commit xeno heresy if you want it.<br/><br/>Void Shield upgrades won't be easy though; the only thing you can really add is Castellan shields, which are obscure archeotech.  You might as well stick in a teleportarium instead, because at least those are easy to find lying around.  (now, finding one that won't make you beg for death after you're transported; much trickier)
