Nether Earth

The player controls a flying machine which can fly over any part of the play-area and is used to command the player's bases and robots. In essence it replaces a mouse cursor, but it can hinder the robots' movement. The player must build robots and give them orders to seek out and attack Insignian robots and capture neutral or enemy factories to increase production and thus aid the war effort. Once a robot is issued an order it will keep being active until all its targets have been conquered or destroyed, the robot itself is destroyed, or other orders are received.

The ultimate objective is to capture or destroy all the enemy bases and thus win the war. Everything takes place in real-time with the action being ongoing rather than turn-based. Because the player's view of the battlefield is limited to where their flying-machine is, much of the front-line fighting is left to the machines whilst the player concentrates on building more robots. However the player can choose to take direct control over one of his/her robots and effectively use it in a commando style to capture factories and bases and to destroy enemy robots.

The player takes the control of the human side in a war against the mysterious Insignian race. All of the warfare is carried out by enormous military robots.

An open-source remake of Nether Earth was completed in 2004 and is available for Windows, Linux and OS X. Another remake is available for iOS.
