Currently, the upgrades that y'all have given Salvation are:
-Exterior energy shields
-Regenerative hull plating
-Improved interior defenses (in case the New Decepticons try to board the ship again)
-The Omega Conflux
-Allspark holograms (to add a little bit of narrative tension- they show Primus's vital signs, basically)
-A ground bridge
-Improved facilities for Facelift, so he can give your characters better mods.
-And improved engex distilleries in the pubs (because why not?)
Current and future upgrades will be added to Salvation's bio as y'all find them.
