I make a little mod like "improved Interceptor - Retaliator". Thanx Shadow for mod example.
It allows to build modified Skyranger (Skyranger-M) after researching Alien Alloys and UFO Navigation.
Skyranger-M in compare with original Skyranger have better: speed, acceleration, more fuel and more armor.
If somebody can repaint Skyranger (to see the diffirence between original Skyranger and Alloy Skyranger) it will be great.
Also i think that it is a little bit stupid bug of original XCOM game that SKYRANGER and INTERCEPTOR sold for free. WTF? O_o
You buy craft for 0.5-0.6 million dollars and then give it to somebody for free? Really?!
Now it can be sold for ~2/3 of original price.
