Worms 2 Armageddon

Create a new human team or use a human team which you have created. Put the super fort match settings of your new/old human team to one of the new Forts. Play a lokal Super Fort Match game and select your human team and add a computer generated human team. The computer generated human team must surrender. => Your human team must win.
After a win, change the settings of your team to an new fort.

The new forts are: Construction, Kev's House, Cottage, Pagoda, Acropolis, Temple, Turret, Wicker Worm, Pyramid and Siege Engine. - Thanks to AdolphMarx for this information

Do this for all of the new forts. After you win with the last new fort the achievement pop up.

For anyone that might still play this or is coming back to get achievements like I did.

First you want to go to "Customise" and then "Manage Teams". I created 10 teams (labelled 1-10 because it was easy). For each team I selected a different Super fort by hitting RB and going to Super Fort and scrolling over until I go to the new Battleground forts. The forts you will need are Construction, Kev's House, Cottage, Pagoda, Acropolis, Temple, Turret, Wicker Worm, Pyramid and Siege Engine.

After you have done this just go to a local game select your first team against another "human" team and have the team that is not linked to your account surrender using the white flag icon. When you get back to the selection menu, remove both teams, then select your next team and another human team and repeat the process until the achievement is unlocked.

Can't Settle Down?

This is the fastest way but it requires a partner.

1st step: Customize your worms under "Manage Teams" both players change to what ever fort they would want, I would recommend starting with construction.

2nd step: Go into xbox live, custom match, settings must be the team you made, Match type: Private Match, Game style: Super forts.

3rd step: When both are in the game just have whoever starts first surrender using the while flag by pressing B and selecting the white flag Icon.

4th step: Immediately start it again after returning to lobby and give the other person the win.(person who didn't forfeit match will do it now).

Repeat all 4 steps, everytime you both win make sure to go back to the Customize and change your super fort to the next one to the right. You will get it after the 10th superfort change. This takes 10-20 minutes depending on how fast you do it.
