Pre-turn: I look around and see that we have twice as many planets as are left to conquer. I also note that all remaining planets are in range and scouted.
2480: I decide that it is time for an All Out Onslaught of Doom (AOOoD).
I start sending half the population from all our backline worlds, coordinated to hit their targets in 7 turns. First turn sees the launch of about 600 million troops. More will join the all-out onslaught of doom when their travel times dictate.
2481: Nazin has 21 bases, which fall, along with 34 pop to a stack of 700+ AMBs. I really need to split this fleet to avoid accidental genocides.
Our 157 troops easily defeat their 66 remaining pop but discover nothing from the 367 factories. The Darlocks have improved eco, but then again, we don't need it.
I send out more troops to join the onslaught, and scrap our obsolete missile ships in favor of the Piranha: manuever 4, graviton beam and comp level 4. I'd prefer a better computer to cope with the Guardian's computer tech, but it's the best we have. Unfortunately, the hard beams wouldn't fit on a tiny as I'd prefer 8-12 damage against shield 5 over 1-15 damage against shield 9. We'll need a lot of these if we want to take Orion.
I change all ship building to Piranhas. I also split the fleet into three offensive groups to go around and take out missile bases, and leave a good portion to defend Nazin.
2482: Altair is readied for the troops ships. The Darlocks congratulate us. I will send some ships to safeguard Altair, since we have yet to assimilate this race, and I don't want them destroyed before we have the chance.
2483: More troops!
Unfortunately, the spud at Uxmai has been glassed by one of the AIs. I had planned to have that be the only planet to be spared the AOOoD. That would leave a chance to hit Orion before taking Uxmai. Instead, I stop sending troops to Ursa (only 27 currently en route), which will leave that as the sole planet to survive the Onslaught. Lest any of ye have any doubts, know this: More than 1.3 billion brave Rock soldiers are now sailing among the stars to bring ultimate enlightenment to the rest of the galaxy. There can be no stopping this landslide.
2484: More paths are cleared for our troop drop ships. T minus 3 turns.
2485: I managed to get all four races to congratulate me for attacking everyone at once. T minus 2.
2486: We have control over the orbit of every planet. T minus 1.
2487: Culmination of the All Out Onslaught of Doom. We win in a landslide.
I redirect all ships in range to Uxmai to greet the last Bulrathi ships, and to regroup for an attack on Orion. Any ships 3 turns out head straight for Orion.
2488: Destroy Bulrathi Fleet at Uxmai.
2489: Launch fleet to Orion.
2490: The Guardian proves to be too fearsome a foe.
VS.
Our piranhas can only hit for 400-500 damage per turn, and the NB's only 50 or so. Not enough to overcome the auto-repair. The Guardian on Hard requires a bit more tech than we had for the Piranhas. If we could get a Hard Beam on a Tiny it would probably do the trick, although it would really be nice to get a better computer as well.
In the meantime, Ursa recieved a couple hundred million elite Silicoid soldiers. The Bears were easily convinced that resistance is futile.
Long Live Emperor Mauna Loa!
I've uploaded the save from just before the AOOoD if anyone wants to watch it, or try to put together a better Orion killing fleet using the new tech we capture.
