Overall: 9.1The game overall is pretty simple and the objective is clear, like most arcade games there is no long drawn out plot and it is easy to understand. All you have to do in the game is manage to stay alive and destroy all of the space stations by either shooting in the central core to blow it up or by shooting all of the 6 units that it is made up of to blow it up. You must also avoid floating asteroids and cosmos, space mines, enemy ships and anything else they shoot at you. The ship fires in both front and back directions to destroy enemy ships and the location of ships are displayed on the radar and their relative location to you. Any ships left are shown in white, space stations in green and attack formations in red in their corresponding shape of formation. I scored the game a 9.1 overall because the objective and game play itself is simple and it stays the same all throughout the game.Graphics: 8As I have said in previous reviews of these arcade games, they are not known for amazing graphics, these games were some of the first and the graphics and animations are simple. I rated it an 8 because although they are simple, they still look nice and the sprites for the enemy ships and stations look nice. The game's graphics are pretty much like your standard arcade game with an 8 bit pixel screen, so they are very simple but nevertheless pretty good.
Sound: 7The sound of this game is also like the graphics, simple and standard, there is a blast of sound when the ship takes off into space and there is an alert when you run into enemy ships or there is a condition red. There are also explosions when you crash into other ships or when you blow up the space station or other ships by shooting at them. It does provide for a nice little game enhancement background and it does make it seem more realistic even if it is a little simple. So it does provide a gaming environment rather than a boring soundless one. I rated the sound a 7 because it is simple but it does make the game a little more interesting and fun to play.
Addictiveness: 5This is no different from most arcade games where you just want to keep playing it over and over again, simple as the game may be that is what makes it fun to play and it makes you want to keep playing and setting a high score. I usually play this game more than once when I get into it, I may set a decent score but I usually make a few mistakes on some of the levels preventing me from getting a higher score, so I usually try a few more times before actually calling it quits. I gave the game a 6 for addictiveness because it is addicting like most arcade games, but it is a little bit harder then some other games like pac man where the objective is just to finish the maze whereas this game has multiple obstacles such as space stations, enemy ships asteroids, cosmos and space ships always surrounding you and ready to attack, so it does make it a little bit harder than a more simple arcade game where the objective is much more simple, so I guess that does take a little bit away from the addicting factor.
Story: 4Okay, again games like this don't really come with a back story that explains and elaborates on why you are in a spaceship sent into space to destroy enemy ships and fly around and destroy things, no, these games come with an objective over a long complex storyline. So as I said before the objective of this game is to destroy the enemy ships as well as the stations by shooting their core and make them explode. After clearing the given amount of ships and stations, you move on a level. I rated the story a 4 because it doesn't really have one, but instead it has an objective that is easy to follow and it fits in with the game.
Depth: 5 It is just one of those games....it can go on forever and they make it more challenging and after the first 5 levels it becomes harder to avoid all of the obstacles in space as well as avoid being shot by the stations or enemy ships. And also the chances of getting condition red are more prominent because more of the yellow spy ships report back to the stations, and then there are always the attack formations which they send on you, multiply the amount of ships in each attack formation, 5, by the amount of stations out there which would be X and then you find yourself swarmed in ships that are ready to attack you at any given time. So it is really no different from any regular game out there, the game gets harder as you move up into the higher and more advanced levels. I have maybe gotten into like level 20 or so which I think is funny because I got that score while playing with a joystick, and my high score was like 105,300 or something along the lines of that, and I can never seem to beat that score with a regular gamecube controller which I find funny. So I rated the overall depth of the game a 5 because it is like all arcade games where it can just go on forever and just continually get increasingly harder to stay alive and complete the objective of destroying the space stations.
Difficulty: 5The actual control difficulty is simple and there are only 2 functions, moving with the control pad and also shooting which is the a button for me on a gamecube controller when I used to play it. It is simple and easy to learn the controls that is the easy part. The harder part is trying to stay alive throughout the game without being swarmed with enemy ships surrounding you and space stations firing in all directions, that is the more difficult part about the game, and it will only get more difficult as you manage to get into the higher levels of gameplay where it becomes more tedious to manage to stay alive. I scored the overall difficulty of the game a 3 because it isn't hard to pick up on and I would have given that separate part a 1 alone, but the rest of the difficulty's score comes from the gameplay itself which is the more challenging part that makes up most of the final score of the game's difficulty.
