Unbelievable find on ruins!

[Xrati]

There are two types of ruins. Ancient ruins and Anciet ruins unique. The 'unique' will give you one of four techs that you can't get within the game at all. They are Massive shield depleter, Massive engine depleter, Massive planetary shields and Neural net. The other ruins will give you a generated number of tech levels at random. You can learn more about this in the map maker/editor program that comes with SEIV.
