peh, I spent the entire yesterday making the Amaterasu an invicible super ship with a specail seekret method to kill it (oh how I love you Esarai for that big, long hangar bay area and the severe case of trench run syndrome it suffers from).
Hmmm, there are interesting things. Where can I get the sentries and the cruiser/destroyer in the last screenshot ?
The "sentries" are atcaully ships...well, you could think of them as mobile sentry guns.

I made them myself when a few days ago while learning to model/UV/texture. Not sure if they're actually good enough to post, I'm afraid I'll get ripped to shreds D:
The ships in the last screenshot are the Hurricane (600m variant), and the UEFg Narayana fropm BP (esarai ver.)
