This Phoenix version from Irecsa/G.G.I Corp., marked as 'set 4', is likely another iteration similar to the previous sets. Any differences from previous versions could be subtle changes in the gameplay, graphics, or sounds. The core gameplay of piloting a spacecraft to eliminate enemies remains the fundamental aspect of this version, just like in the previous sets and the original Taito release.
