What about the UFO and 10 relic archievement? Do they need be won in one world? Do they need to be accomplished only in 1 era?

50 colonies to?

yes

its not clear aister does the 50 colonies archievement mean 25 in a era and then the next era 25 to is that possible?

No, the 50 conquers achievement for example, you need to have conquered 50 colonies or more in one era, not spread out over several different eras.

and the ten relic one thats just for your relics you conquer in the whole game on every world? Cause gatching 10 relics in a era seems impossible

I believe u asked yes/no questions, so I answer yes to them all...

those achievements must be get in one era. Which means even if last era u catched 49 UFOs, the next era u have to re-do it again.

And I believe 10 relics achievement are for solo worlds.

mine english very understandable hehe.

ok so 50 ufo in 1 era man thats not easy and ten relics in 1 era what the hack is there somebody who has made that archievement. And i for example i have a relic and i have a buddy and he send his quad to take it and when he is on i send the squad back to retake it and do this 10 times means archievement?

Is there somewhere on this site with the list how to win thos archievement that would be very handy

I don't think there is... the guide I meant

but yes I think the relic problem can be solved by that
