Armor Games

I just started playing Frontier today and I noticed on the achievements that you can own cities.  Well, i looked all over and I couldn't find where to take over the city. Please Help?

You have to win in a battle against the city with the option at the end of the travel sequence.

It's pretty hard.
You should probably get vanguard, a team for 4 other people who have decent attack and/or defense, and equip them with the best armor/weapon available.

Well, some of the achievements require you to capture a whole load of cities.

Your best chance would be to get a vanguard/medieval tank (i use vanguard), and equip your whole team with the best armour and weapons

Good Luck!
