I have played a couple games as the Advent, and I built the deliverance engine. I fired it at enemy worlds but nothing seemed to happen. I searched the forums but only got a few hints of its function here and there. It increases your culture at a planet, and it MAY cause the planet to eventually go neutral. It gives you ships more attack damage (?). If this is so do you have to fire at a planet where your ships are already fighting? How is the Deliverance Engine actually used and what are its effects? If someone could post their successful experiences with the D.E. it might help also. Thanks.
