The war raging between the ESME'S and MATDEN'S ensured they never helped each other. But today they are running out of resources on planet Tern. Use the space craft to travel from planet TERN to OLAD. Space craft can accomodate two of them and atleast one is required to operate it. At any given time, do not leave more Matden's than Esme's at any planet. Select them using key 5 and use key 2 to launch the spaceship.
