This can be a frustrating achievement as you've got to re-create every single match and re-invite your partner if you are doing this on XBox Live and your the host.

You can either do this achievement with additional controllers or via XBox Live with a partner/s. You can also do both methods in which you and a partner on XBox Live assign a 2nd controller each, or have 1 person on XBox Live by themselves and another with 2 additional controllers plugged in, giving 3 players.

For this achievement though, you only need 1 of the above regardless.

If you are planning to host the match, simply select XBox Live, then Player Match. Assign the the controllers on the Local Players page if you are adding them in. Choose Battle and Create the Match in the Battle Game Mode.

Now these are the maps you need to get to play on in order to get this achievement...

Classic
Adventure Island
Dark Castle
Factory
Giant
Laser Arena
MultiMaze
Pirate Ship
Power Station
Reflectors
Steamworks
Thunderstorm
Time Tunnel
Volcano
Waterways

These are DLC maps for the game and are "NOT" required for the achievement...

Asteroid
Intersection
Charger
Future
Dojo
Resurrection

Make sure the maximum amount of players that can join is 2 and set the number of wins to 1. All the other settings do not matter.

You do not have to change anything for the Power-Up Settings neither.

Once the match is up, invite your partner/s if you are doing this via XBox Live. When the match begins, the players who are losing simply need to move for a moment and then they can plant a bomb to commit suicide.
This will give the sole player in the match a win towards this achievement. Now if you are doing this with a partner via XBox Live, the host can simply restart the match and let the other player who needs a win to go ahead and do so.

Once the map has been completed and you both have a win, you will have to return to the main menu of the game, follow the on-screen instructions and re-host again on a different map. So overall this achievement is going to take a short while to get done. Probably an idea is to grab a pen and paper and write down the maps you've got to do, then tick them afterwards.

The achievement will unlock once you have won on all of the above maps. You will also get this achievement as well for completing a game on each default map...

My advice to get this is just set the map to random when going for all of the other achievements. I got my achievement like that, without having to go through all of the maps and selecting all of the settings all over again. Set wins to 9 and just keep playing games.
