Destroy the 8 fortresses of the Gulbas empire!
The war against the interplanetary Gulbas empire has not been going well. Intelligence reports state that the Gulbas forces are regrouped around 8 fortresses, but this information has been of little value, considering the heavy losses endured by the Earth's military space fleet. As the best pilot of the fleet, you have been given control of an advanced prototype star-fighter code-named Zaiigar. Your mission - and Earth's last hope - is to destroy the 8 fortresses and turn the tide of this war. But the Gulbas are relentless adversaries and will not lower their guard when faced with a single enemy fighter! This is undoubtably a suicide mission, but Earth may still prevail if you succeed!
Several years ago, the SG-1000 version of Gulkave was originally going to be ported to the ColecoVision by well-known homebrewer Guy Foster, but after reaching over 95% of completion, he encountered some technical difficulties and put the project on hold.
A couple of years later, I personally met Guy at a vintage gaming meeting in Montreal, and we discussed the possibility of publishing Gulkave under the Opcode Games banner, with box and manual. Guy was certainly interested, and he resumed working on the port for a while. But later, the addition of a new baby in the family as well as other responsabilities forced Guy to withdraw from the project once again.
Guy graciously agreed to hand over the Gulkave port to Eduardo Mello, who restarted the port from scratch and made it work flawlessly on the ColecoVision. After I left Opcode Games, Eduardo let me publish Gulkave under the Team Pixelboy banner.
