i play endless longtime and have some exp want to share,use it rush in endless diff will be easy.i called it "use enemy money kill enemy",the core is try best to earn money from diplomacy and upgrade ship(not build) to rush.

first,my custom race trait:

merchant 2 (add 2 trade route,we rush so no time to build trade post)

naive 1 or 2(we use diplomacy,so this can help maintain your system happy 4*7=28 which is better than optimistic)

dust recycler 2(we need more dust to upgrade more ship rush,useful early)

scientist 3(we need trade tech from Ai take dust,so sci superior is ness)

optimal structure 2(+30% tons for ship,more tons means ur fleet more armor and survive)

spendthrifts 3 (add negative points so we can add above trait,cause colony dust income will be half until 30 turns so produce dust by yourself is useless especialy early time)



affinity:all,sophon is good for science super can trade more dust

8 players( must be 8,cause 1 tech can trade to 7 enemy),normal size galaxy.



so here comes my guide,try reserch most first class tech(40 points tech)and then tech colony arctic which speed up ur ship and arctic colony will help science.and then reserch diplomacy tech which can trade money.same time use ur scout travel space,20-30 turns ur scout should have contact with all 7 opponent(scout must tactical combat withdraw otherwise first encounter enemy will kill ur scout).most ai have it's own favor tech,so trade tech between Ai will earn u much dust,and cause u have merchant2,ur get 2 trade route auto help u more.i mostly complete this before 20 truns.now it's time for rush,build ship only with hull+2 ind armor(upgrade cost only determine by target ind require no matter what original ship is),the ship should be 27 ind only,u cab easy build 2-3 ships per turn in ur home plant,and upgrade cost to missile/deflector ship only 60-80 dust each,u can build vast fleets with diplomacy money like this and rush anyone,later u can reserch tech unlock cruiser,one invasion cruiser+5 destroyer fleet(7cp) will take most ai colony in max speed.
