This game is based off of a coin-op of the same name (or Savage Insects). This is also possibly the most appalling port of a shooter ever.
When you start the game, you have the option of 1 or 2 players. It's not likely you'll be able to find a cartridge of this game and a Famicom (or a modified NES which plays Famicom games), much less another person to play it with you, so 2 player is out of the question. When you start the game, you are greeted by your ship coming together and an ear-piercing noise. You have invincibility for a few seconds (which is totally useless) and invincibility makes an ear-piercing noise. That's two strikes against the sound already. The music doesn't fare any better. The music consists of a very few tracks which all make you want to tear your ears off. That's three strikes already, and we're not even through the first level. Also, the enemy formations seem very similar, only sometimes getting a very small change. There are power ups, but there only seems to be one power up to your ship's gun, the others either turn all onscreen enemies into fruit, or downgrade your gun. The gun upgrade doesn't seem to do anything anyway, so this is mostly harmless. The graphics are really dull, and there isn't much change between levels, mostly. The gameplay is just your average shooter, except worse. The enemies are mostly giant insects (which explains the arcade game also being known as Savage Insects) and machines. The enemies are lame, and the gameplay fares no better. The game has these little "Hi-Point Areas" where most of the background disappears, a bunch of skull enemies appear and move down towards you, and there are power ups that turn the enemies into fruit. These "Hi-Point Areas" don't add much to the game except a change of music. The gameplay is just as I said it, your average shooter. Except this shooter doesn't have much different from "shoot enemies, get power ups, defeat bosses, don't die." The game is of average shooter difficulty. Not really easy, not too hard. The game doesn't have an ending, it just warps you back to Round 1. Interestingly, there was a contest or something where if you took a picture of you having a certain score, you would be sent a sticker or something to put on your cartridge. I don't know if anyone sent a picture, but if they did, they had either played every single other shooter on the Famicon/NES, they had no shooters/games besides this one, or they wanted the patch to show their friends. Overall, the game is a shoddy port of an arcade game. This could've been good, but it was ruined by shoddy porting. Even though the title screen says otherwise, this game was NOT developed by Capcom. Capcom handed the job to a company called Micronics instead. That's probably why nobody's ever heard of them.
