Good as a 3D effect, not so good as an actual game
The ship in the game has two main functions. You have the standard weapon you see in every other shoot-'em-up game to destroy other aircraft enemies. You also have bombs you use to destroy enemies on the ground. I felt this game mechanic didn't work as well as I thought it would because to destroy ground enemies, you would have to have your ship in a restrict location on the screen. This is very difficult to do when you are trying to avoid other enemies and their respective bullets.
The overall game has a very uneven difficulty curve, ranging from enemies that are too easy to destroy to enemies that are near impossible to avoid. Also the 3D, while impressive to look at, can be very distracting at times making the game more difficult than it already is. The graphics are pretty good, I will give it that but it would have been nice to see more variety of backgrounds assuming that the background stays the same throughout the entire game (I have only made it so far without losing all my lives). The audio is what you would expect from an arcade game of this type, but I still find it painful to constantly hear this uncreative loop of a melody mixed with the grinding noise of your ship firing at enemies.
If you are already a fan of Xevious, I am sure you will enjoy this 3D adaptation. If not, I would skip it as I am sure there will be other 3D adaptations of better shooters in the future.
