Budget Defense

This is a free placement tower defense game. At night, you need to sell the extracted oil at the fluctuating market price to obtain gold coins, which you can use to build more oil extraction machines and defense towers. During the day, work together with the defense towers and tanks to block the enemy's attacks. Achieve a balance between economy and defense, resist the continuous waves of attackers, and protect your base.

• Optimally combine different oil extraction machines to maximize the amount of oil extracted.

• Different oil extraction machine bases bring about different attributes for extracting oil.

• You should act like a petroleum tycoon and sell on the days when the oil price is highest to maximize the profits, but ensure that the base is not destroyed during the day.

• Among the obtained gold coins, you need to decide whether to build more oil extraction machines or more defense towers.

• The freely placed base of the defense tower also has different attribute bonuses. If the placement is appropriate, the defense tower will cover more enemies.

• Build different cannons to defend against different enemies. Like in the original Kingdom Defense War, there were four defense towers. The towers have different branches.

• During the battle, there will be air drops of supplies. Collisions will extract different items, such as nuclear bombs and pulse waves, which will cause massive damage to the enemies.

• A light mod of patchwork, by purchasing different bonuses from the store, the speed, damage, defense, etc. of the tank will be increased, enhancing the enjoyment of the tank.
