country of origin indicates New Zealand, making this the only game title to come from there. wanted to be sure not a typo, Hot Copter is the prototype version to Laser Hawk of which the Red Rat release is said to be U.K.
press the B key on title screen to toggle invincibility on-off. level # shows letter B added to it when invincibility is on. my copy of Laser Hawk has this cheater also.
