One morning in a certain country, a volcano that had been worried about for some time massively erupted, coughing up tons of rocks, ash and magma and still rains downs on the town.
The people, however, have not panicked all because a brilliant minister had a state of the art defense base constructed in advance.
It's finally time for the defense base to go into action!
Just then an unbelievable message arrives for the minister.
The defense commander got a stomach ache after eating some cake he found sitting somewhere and is bedridden.
This is horrible. No matter how high tech the base is, it can't operate without the commander.
The minister thinks quickly and makes a decision.

"Recruit a new defense commander right away!"

In the blink of an eye the call spreads through the town.
The message reaches you, who are worried about what to eat every day, and you leap at the chance.
You get chosen as defense commander right away. After all, you were the only one who applied.
Everyone else is holed up in their homes, afraid, or are just pretending not to have noticed the recruitment and are proceeding with their lives as normal.
But they're not you.
Can you keep everyone safe and enjoy a delicious breakfast?

Surprisingly, a message comes from the sick defense commander.

"Now don't waste ammunition(wink...),"

is what it says. Good luck!

Urgent Recruitment for Defense Commander! is a game where you protect 6 towns by intercepting volcanic debris that rains down from the sky.

★Protect the towns by destroying the volcanic projectiles!
The volcanic projectiles fall slowly from the top of the screen toward the towns.
You fire artillery from the base and must intercept the falling projectiles before they hit the towns.

★Be careful with ammo!
Regardless of the base being state of the art, your ammunition is limited.
If it falls to 0, all you will be able to do is look on helplessly as the cities are destroyed.
Just as stated in the previous defense commander's message, use your ammunition wisely.


★A sudden turn around with items!?
When you destroy volcanic projectiles, they drop items.
These items fall toward the base. If they make it to the base in one piece, you can acquire them.
Watch out for one thing, though. If the falling items are caught in an explosion they will disappear.


★A surprise when towns level up!
The towns level up by 1 when you clear a stage.
The higher a town's level, the better it's bonus ability and when a town is leveled all the way up it will cooperate with the base!
Raise all of the towns to the highest level and build a strong defense city.


★Go for a high score with chain hits!
Your rounds aren't the only thing that can destroy the volcanic projectiles.
A volcanic projectile that gets caught in an explosion gives off an explosion about as big as your artillery.
When a volcanic projectile gets caught in the explosion of another volcanic projectile, it becomes a chain hit and the points you receive are progressively doubled.
Aim for a high score by actively going for chains.

★Go for a high score with Double Points!
One of the items dropped by the volcanic projectiles is the Double Point item.
If you acquire this item the points you receive will be X2(doubled).
By repeatedly acquiring this item, the factor applied to your points can go up to X8.
On top of that, the Double Point effect works with chains!
