[Game purpose]
Enemies and allies own a resource called water.
You can obtain resource water by defeating an enemy carrying a tank in battle.
If you defeat an enemy with a yellow tank on his back, the enemy's resource water will decrease and you can obtain resource water.
The goal is to fill up your ally's resource water.
After that, you can find out the final objective by looking at the enemy's data panel that can be viewed at any time during the game.

[Game features]
