Well, after painting some marines now it is the turn of Machina. So far I have painted AI, Hunters or hair dryers, Exterminators and Scanners. I still have to paint a Missile Tank and a HQ.
For the AI I converted an Epic Land Raider by simply putting half a ball on it.
For the Scanner I used a robot from GZG
The Exterminator is from Khurasan
Another one from GZG
