Which war do you want to fight? Generate your own scenarios with Advance Wars: Dark Conflict’s Design Room and battle on your own creations. Then share them with your friends or the Advance Wars community via Nintendo Wi-Fi Connection.

Easy to use and incredibly deep, the Design Room lets you create and store up to 50 custom maps, using all the battlefield elements that make Story mode so challenging.

The size of your maps can be as small as a 5-by-5 grid, as large as 30-by-30 and all sizes in-between. The Design Room features a Wipe Clean function that fills your entire map with one terrain element from Sea, Plain, Mountain or Wood. Once you have your elemental base, you can place any of the game’s units, terrain features, structures or special items such as plasma shields, meteors and fire.

You can also choose to have the game auto-generate a map, and then you can edit the map from there. Up to 50 units can be placed onto any one map, and you can customise the AI of each individual unit, including adding a default Commanding Officer to a unit.

In addition to the look of the map, you get to determine how the map plays. Customise the game rules for your map. Will your map be especially nasty covered in the Fog of War or will clear skies prevail? Maybe you’d rather set the weather to random. On top of this, you can set the starting funds and income generated by each base, the fighting habits of the computer AI or put a limit on how many days you have to win the battle.

After you’ve finished creating your battlefield masterpiece, go to the Single DS Play menu and try to score a victory on the map. If you can conquer your own creation, you’ll be able to share it online via Nintendo Wi-Fi Connection.
