Mission in Space: The Lost Colony strategy guide.
Nice strategy guide :)
Here’s a video walkthrough showing the diamond medal being earned on mission 12 with only 30 skill points invested (challenge VI) :
Video on youtube
Of course this isn’t a precise how-to, but you can see which skills are chosen and the general behavior of the troopers. Try placing your troopers like shown on the video on turn 1, this can be helpful, especially for the bomb.
Hope this helps ! If you want another video of another challenge or diamond medal, don’t hesitate to ask.
