Okay, so I know some stuff about the battlefield but I have a question. What is the difference between Homeworld and Mirror? They look the same to me.

Mirror takes some time to get onto the field, while Homeworld doesn't. The time it takes to get onto the field for Mirror depends on the squads research potential.

For everything else, they're the same.

What Aelisk said. Also, when I first had my squad and they were squishy newbs, I noticed mirror was where other weaker squads tended to hang out. So it seems to be a place for the newer or weaker squads to get a good foothold and get the hand of battles before moving to the tougher homeworld.

Okay, thanks guys!

Er, one more question.  I'm on the mirror battlefield and my pets say that they are on the battlefield but I don't know where they are. I've checked all the little regon things but my pets haven't popped up on any of them.

Did you hit the magnifying glass icon? You should see a number at the top of the map - That means you're in the middle of researching your way there. When that number hits 5000, you'll be able to land on the map. Then after you land, your squad(s) will show up as green.

Well, I'm done researching because it says "Ready to land" or something like that. I just don't know what that means when all of the pets in my squad say "On battlefield" as status.

Nevermind, I figured it out. Thank you!
