Gun Nac is a vertical shooter by Compile and published by Tonkin House. Iota Synthetica is an artificial solar system on the far side of our galaxy. Humans have been living there for years and life is prosperous in all ways. But things are about to change - one day the idyllic world is hit by strange cosmic radiations which bring some unexpected side effects. Inanimate objects suddenly come to life, animals turn into large monsters and all attack the same targets - humans. The player takes control of Gun Nac and flies to the rescue. The eight artificial planets of Iota Synthetica must be cleaned up and each one has its own unique theme, from the Lunarus moon and its army of evil rabbits to the aquatic world of Atlantajorja. The fighter starts rather small and weak but power-ups can dramatically increase its strength ten-fold. Five weapons are available for the picking - Vulcan/spread gun (Blaster), explosive-gun (Screen Buster), homing waves (Search Driver), flame Thrower (Dragon Napalm) and lasers (Wide Beam). Special wings can be equipped to increase the ship's firepower and to help it sustain enemy hits. Finally, the game features four different bombs based on elementals - fire rotating rings (Fire Bomb), wall of ice (Blizzard Bomb), thunder lightning (Thunder Bomb and water rain (Water Bomb). A grand total of twenty bombs can be carried at the same time. Some ships drop money which can be collected by the player and used to purchase/upgrade weapons or to release valuable bomb icons in coming levels.

Miko The original Japanese game features a slightly different story than the American version. A Miko (a Japanese female shaman) is called to investigate the situation. She's the one who ends up summoning the Gun Nac. At the end of the game, she reappears and receives a trophy for her performance. The shaman was completely omitted from the American version - however, the original Japanese screens are hidden and can be seen by unlocking the "Death & Non-Death" mode (see the secret section).

The second level takes place on a fire planet and the Japanese version features unusual enemies such as cigarettes, matches and lighters. These were obviously removed from the American version and replaced by large bullets, spaceships and factories.

This might be a coincidence, but it is interesting to notice that Gun Nac levels seem to be based on the days of the week:

Stage 1 - Moon. Getsuyōbi (monday) means "Moon day" in Japanese.
Stage 2 - Fire planet. Kayōbi (Tuesday) means "Fire Day" in Japanese.
Stage 3 - Ocean planet. Suiyōbi (Wednesday) means "Water day" in Japanese.
Stage 4 - Forest planet. Mokuyōbi (Thursday) means "Wood day" in Japanese.
Stage 5 - Money planet. Kinyōbi (Friday) means "Gold day" in Japanese.
Stage 6 - Earth Planet. Doyōbi (Saturday) means "Earth day" in Japanese.
Stage 7 & 8 - Artificial Sun. Nichiyōbi (Sunday) means "Sun day" in Japanese.

Miko Reset the game and wait for the introduction sequence. There, hold A and B together until you see a new series of screens and the words "Death & Non-Death Free Select Mode Ok!". Now enter the config.sys configuration screen and set the new Death option to Non Death. As a side note, the secret screens displayed during this mode are from the introduction sequence omitted from the original Japanese version.
Level Select
Enter the config.sys configuration section. Set the sound test on "05". This should unlock the "area" section right above it and let you choose a level. Interestingly a stage 0 is also available.

Gun Nac is definitely one of the best Famicom shooter ever released. It is Compile at its best - fast, intense with incredibly responsive controls and a flawless gameplay. Some players may show no interest in embracing the game's unconventional and silly tone - evil rabbits, carrot missiles, flying candles, mean toilet rolls, deadly umbrellas and so forth. I personally think it's a welcome dose of innovation to a genre that is serious in nature. There is no coincidence if Gun Nac plays like Zanac and shows how well Compile mastered the genre and the Famicom hardware. I'm really impressed on how Compile handled the Famicom limitations here - the game is incredibly smooth without much flickering (except in a couple of places), even when the screen gets filled with enemies and bullets. Finally the game features a great difficulty curve and a cleverly designed option menu allows to crank up the heat if necessary. All in all, Gun Nac is an absolutely fantastic and fun shooter.
