I've just started a WH40K test campaign for v2.6. This is the setup:
• Starting population is two billion with standard installations for that population size, except for 800 Maintenance Facilities instead of 600.
• Research Points are double normal to allow for the variety of starting weapons.
• Starting Build Points are double normal, on the assumption the Imperium has been building up the largest army and fleet it can support before venturing into the galaxy.
• Ruin chance is increased from 20% to 25%.
• Enhanced Invaders, Enhanced Precursors, Enhanced Swarm and Raiders are active
• System Count is 30 for Raiders, 60 for Swarm and 100 for Invaders.
• NPRs can activate Precursors and Raiders
• Ten multi-system NPRs using 2 + 4 empire radius. 60-120 LY
• NPRs generate other NPRs with a 10% chance.
• NPRs generate Precursors and Raiders
• Minor Races set to 100%
• Limited Research Admin
• Research speed 50% after game start
• Hostility Modifier +20
• Survey Speed 25%
So this will be a challenging campaign. However, I think this is the best start to a campaign ever! Firstly, I found a Deserted Intact Colony on Mars, then four jump points, at 0.5b, 1.5b, 2b and 2.5b. One led to Alpha Centauri.
On Alpha Centauri IV, which only needs 0.09 atm of oxygen to be an ideal habitable world, there is a Ruined City and a dormant construct.
On Alpha Centauri V, which has a thin nitrogen-oxygen atmosphere of 0.18 atm and temp of -43C, I found Deserted Intact Cities!!
I only have 2 XEN and 2 CON formation, so constructing ground forces is going to be a major priority. The only downside is that one of the four jump points led to a system 70 LY from Earth, which I suspect is within the empire of a multi-system NPR. So I need to exploit my ruin riches before a much more powerful NPR finds Sol. Fun times ahead!
