Concept: You are the Guardian, who for some reason or another is on a star called NAJU, which has been invaded by aliens. The objective is to exterminate them, obviously. It's not all that original, but the game itself is. The combination of the overworld Zelda thing and then searching out the corridors for the underworld fighting is a great one. When you beat a certain underworld level, you get keys to tackle more challenging corridors. Overall, pretty good. 17/20
Graphics: The graphics are average to above average. The bosses are well detailed, I suppose, and the colors aren't all that bad. However, the graphics aren't really that important in this game. Bonus for having many types of enemies. 15/20
Sound: The sound is pretty decent actually, since I can remember 3 or 4 tracks off the top of my head. And this is an NES game, with MIDI tunes. I even plan on using some of the Guardian Legend tunes in my game, which is saying something since most of the tunes are action type things that aren't used often in RPG's. 19/20
Gameplay: The gameplay is pretty easy. Just move and fire. It's not that simple, though, because there are different weapons that you can pick up throughout the game and use them. Probably about 10 to 15 of them. The game is pretty challenging, so you'll need them as you try and unlock the ten sections and many corridors. I've already mentioned the overworld/underworld, and the underworld fighting is different because you are in a ship thing that moves in all four cardinal directions while firing at the things that come at you. It's easy control, but it is challenging. 18/20
Fun: Obviously, a problem for people who get frustrated easily will be the challenge. But I like challenge. Most of the game's fun comes from unlocking the corridors and beating them, while moving through new sectors and getting more powerful while finding new weapons to beat down the enemy with. And it's way more fun than it sounds. The most annoying part about the game is the password system, which is used in most NES games. I hate it, though. 17/20
FINAL SCORE: 86/100
