OK, this one DOES look like it will be much harder.
I adjust one of the planets to get a colony ship a turn sooner.
Xudax is at its pop limit, so I tell it to terraform a bit harder
I like our research choices so far except.... Why the heck did we go back for Barren when we had Tundra?? I know its cheap, but what good is it? Will it let us make LR colony ships? I don't do the spreadsheet thing, so I admit I may be missing some subtle trick here.
2351 - The first colony ship completes, heads for the nearer of the 2 Tundra worlds. I think we may get a chance to scout annother couple plantes. I want one more Scout, but a single click at the home planet yeilds 2. Oh well
2352 -
2353 - The second colship completes. I send it forward for redirection.
2354 - Hyper-V Rockets hit, Choices are: Gat L, Hyper-X, and Fusion Bomb. Hoping for one of the Good missiles at 3rd tier, I select Pelet Guns. Bah, I forgot to take Dunatis off shipbuilding
2355 - Range 5 hits - Choices are: Range 6. We select Range 6
Arietis Settled. Scout sent to explore an unknown red planet in the southwest. I send 32 million to Arites from the homeworld, and order it to regrow the pop. The other planets are too small and/or too far for me to want to send from there.
I send the 2 harrsaaing scouts at the white planet forward to do actual scouting. I send a replacement harrasser
2356 -
2357 - DSS hits - Choices are: Robotics III or BC MK III. We follow the Zed Hop™ and select Robotics III
Class II Deflectors hit - Choices are: Class III Deflectors. We select Class III deflectors
Controlled Barren hits: Choices are: Death Spores, Enhanced Ecco, Terra +30, Controlled Toxic. I can't see beelining for ONE planet, so toxic is out. We select Enhanced Ecco
2358 - Xudax maxes factories and pop. A scout arriving at the blue west of the Klackon white planet finds more Klacons there

Our colony ship reaches Arites, and redirects to
Rana.
2359 - A scout arrives at the red along the bottom and Finds size 45 Desert Phyco. We'd sure love to grab this puppy! Only, the Klackons allready have

This means, with the possible exception of one green planet we can't scout yet, we are now completely surrounded, facing the prospect of being a 5PE.
2360 -
Might want to consider making a batch of fighters to defend the tundra planets. I expect a war declaration within a couple turns of contact.
Here is the save.

Edit: It occurs to me that, this time, it might have been worth beelining toxic because we could have also grabed the Inferno planet in the north and got out. Then again, that would have been risky and we did desperately need cleanup.
