In StarForge go into the unit settings and the hp will have 2 boxes. (I will post a screenshot in a little bit)
The first, smaller box put a "1"
The second, larger box is the normal Hp box.
Put that below (I think) 7 and it will give a cool effect. the 7 may be wrong, but I know 5 and below works. I do not think 0 works though.
Look in the StarForge forum for the topic called "HP 2"
ADDITION:
Here is the image. I made the "HP 2" box a light red. This is what you need to make "1".

Here is the HP 2 link:
HP 2Also people may say if you make the "HP 2" box greater than one, it will make something else different. It is only read if it 0 or not.
