We began to scout the area, desperately. What we found were nests: endless nests. Nest too strong to consider tackling.
Far to the north though, on the other side of a forest, we at last found an iron deposit with no aliens living too close-by. Soon we'd threaded a railway track up to it, taking care to give the nests a very very wide berth.
No aliens would attack our little block-house as long as it wasn't generating any pollution, but we'd need to pollute to extract any iron ๐ค Our extraction operation would need defences, meaning a regular supply of bullets. But how to get them there?
The plan was simple: every train would leave our outpost, known as "Certain Death", with a cargo or ore. It would then return with a cargo of bullets, having refuelled and offloaded its ore at the main base.
Disaster was averted, but we were effectively back to square one, endlessly turning ore into bullets to kill the aliens who were trying to stop us from mining ore: a perfect Capitalist Utopia.
Also our outpost had an electric life-line running along the train line back through alien-infested territory: defending the whole length of the track would be impossible, so it could be cut at any moment by a stray alien patrol!
It was a race to research Fluid Wagons so that the crude oil, piped from "Gas Town" to our main base, could be carried all the way to Certain Death by train.
If memory serves we felt that building a pipeline would be too risky: we'd need a lot of metal for pipes, and we'd need pumps at regular intervals to keep the pressure up. And we'd angering the nearby nests setting all of this up - we didn't have the manpower.
The rest, as they say, is history: many hours later Certain Death would be entirely enclosed within a larger perimeter wall, and its historic defences would be dismantled.
At this point in the game were filling acres with iron or copper smelters, and sending the resulting metal plates by trains to massive factories on the other side of the continent.
