Choose the location of your base pump carefully. Once placed, you cannot move it. If another player destroys your base pump, you're out of the game.
As you level up, you'll unlock better equipment such as bigger pipes, more powerful weapons, placeable defense objects and water processors. Water processors can be used to heat, filter and purify the water which increases the flow rate of your pipes.
Ponds will be depleted over time, so make sure you plan ahead.
