Get Source Code to Make my own Personal Version

Greetings Insurgence Team,

You have made an excellent and enjoyable game. I have played it through multiple times now.

I was wondering, due to the game being in version 1.2.7 for a few years now, if I could be given the link or be allowed to have access to the source for the game, to make my own local copy of the game?

I do not wish to make a version that is published, just something for my own personal enjoyment.

Thank you.
