I try to get the "Grab Your Gun And Bring in The Cat" Trophy on PS4, can I do it on skirmish mode or do I have to do it in the campagin? Are they cumulative?

I can only speak for the PC version since I don't know if the console version has different parameters.

However, on the PC, any ship, be it MP, skirmish or campaign, will count. You can kill a 100 in skirmish, 200 in MP and 200 in the campaign and you should still get the trophy.

It's been a year...but I seem to remember that trophy popping while doing the campaign. However..the Endeavor/Evolution trophy is still glitched for me. Hopefully you have better luck with the 100% then I did.
