To fight an enemy aim the cursor over the target group until the cross-hair turns red and press the action button. Your troops will charge into battle fighting all in their way. To construct a base camp a mobile drill rig must be positioned over a bubbling oil slick. Oil is then drawn from the ground and taken to your main outpost. A Power Unit supplies electricity to the buildings.
Barracks allow infantry to be trained.
Machine Shops provide vehicles. A Research Lab is used to advance technology and upgrade buildings to provide guard towers, improved troops, stronger vehicles, more powerful weaponry and eventually aircraft. At any time the enemy may wage an attack on your base and you won't have a clue when this is about to happen. This is because all of the terrain that has not been crossed by your troops is completely blacked out. This encourages the sending out of small hit squads to see what danger lies up ahead.
