Additional Info

 * To collect a single OP Left Click it and then select the yellow "Collect ##,###" Button.
 * All Metal Factories & Oil Pumps may be collected simultaneously by Left Clicking anyone of the them and selecting "Collect All".
 * The OP does not have to be full to be collected. A common practice is to collect or "reset" them prior to logging off thus allowing it to produce for the maximum amount of time before the player can log back in.
 * As the player's upgrade needs rise in levels the usefulness of the oil pump diminishes forcing the player to seek additional resources elsewhere ( Enemy Player Bases, Rogue Bases or Deposits ).
 * Many players eventually cease collecting the OP's over concerns about the amount of power they consume.
 * Fortunately even when not producing the OP's can be useful to the player as a form of barricade.  As with all non destroyed buildings a attacking ground force will usually make a path around it assisting the defending player in herding the enemy into a exposed positions or slowing their forward progress.
 * Oil Pump is one of two buildings that are also known as Producers the other being the Metal Factory.
 * Oil Pump's like the Metal Factories are usually considered low priority and placed outside the main defenses when designing a Base Layout due to the relatively low amounts of resources they hold.
 * Like any other Kixeye games the resource used to upgrade the building is never the resource that the building produces. n)
