This game was found out about thanks to Jason Kelk, who pointed me in the direction of the DELTA loader… In that, you will read about forthcoming games on the C64, which includes Starline (See elsewhere) and also Mantrax.
I don’t know exactly what Mantrax was about… but its rumoured to be a space shoot-em-up.
Also I have no information on the people who were to release the game. Though Bob Stevenson and Douglas Hare are confirmed to be the guys behind the game..
Unknown as of yet what happened… most certainly not released…
