Old achievements in new waves

[Victoria]

Does anyone know if you can still complete the achievements from previous waves once the new wave starts? :)

We assume you can, but instead of receiving a gold check, you will receive a green check (for filling the bar).

 

The only way to find out is to try :)

Yes, you can still complete old achievements even after a new wave starts. Have confirmed this through a friend :)

What about the "Complete a faction challenge"? Is that just through the second wave's factioned enemies, or is that not a time-reliant achievement?

Again, the only way to know is to try it. Go get a faction challenge, complete it, and see if you get it (I suspect you would, but I didn't code the war).
