Konami's Salamander sequel on Famicom, as Life Force in the West. Two-player co-op, new stage themes, organic worlds.
Life Force — Salamander 2 in Japan — was developed and published by Konami for Famicom in July 1988. A sequel and reskin of Salamander, the game sent Vic Viper and Lord British through organic life-form environments rather than mechanical space settings — stages resembling living tissue, veins, and biological structures. Two-player cooperative play was retained from Salamander. The North American version altered the storyline significantly. Life Force sold approximately 1 million copies on Famicom and is considered one of Konami's strongest Famicom shoot 'em ups.
About this game
Life Force (1987), known in Japan as Salamander, is Konami's Famicom adaptation of their 1986 arcade shooter — a horizontal and vertical scrolling shoot 'em up in which two pilots fly through a living organism's interior to destroy it from within. A sequel and spin-off to Gradius, it shared that series' iconic power-up capsule system and became a definitive entry in the Famicom's shooter library alongside its parent franchise.
Key Features
Alternating horizontal and vertical scrolling stages that change the shooting plane mid-game. Power-up capsule system shared with Gradius: Speed Up, Missile, Double, Laser, Option (companion drones), Shield. Two-player simultaneous co-op throughout the entire game — both players on screen at once. Six stages themed around organic environments: a fire planet, a stone planet, the inside of a volcanic creature, and more. The Famicom version differs from the arcade in boss selection and some stage layouts.
The Story Behind
Life Force arrived on Famicom in September 1987, two years after Gradius had established Konami's reputation as the master of home console shoot 'em ups. As a companion piece to Gradius, it shared the power-up vocabulary players already knew but offered a more accessible entry point with two-player co-op that the original Gradius lacked. The Famicom port was notable for its faithful recreation of the arcade experience at a time when home ports were frequently inferior compromises.
Tricks & Tales
The Famicom version of Salamander / Life Force is an enhanced port rather than a direct arcade conversion — several bosses and some stage content were changed. In Japan, the game uses the Gradius power-up gauge system, while the North American Life Force version was modified to use a direct capsule pickup system (collect the capsule = immediately gain the power), making it more approachable for Western players unfamiliar with the gauge mechanics. The soundtrack was composed by a team including Hidenori Maezawa and Shinya Sakamoto.
Collector's Guide
Region & Compatibility
Famicom and NES are the same hardware family but use physically incompatible cartridge formats — Famicom carts have a 60-pin connector and a narrower shell, while NES carts use a 72-pin connector with a wider housing. You cannot insert a Famicom cartridge into a North American NES slot without an adapter, and vice versa. The Famicom itself has no lockout chip, so any Famicom cartridge from Japan will run on a Famicom console regardless of origin. If you are buying a Japanese Famicom cart to play on a NES, you will need a 60-to-72-pin physical adapter; if you own a Famicom, Japanese-market software is your native format and no workarounds are needed.
Maintenance Tips
The gold-plated edge connectors on Famicom and NES cartridges pick up skin oils and oxidation over decades — a gentle wipe with a cotton swab dampened in 90% or higher isopropyl alcohol, stroking along the length of the pins rather than across them, is the accepted standard. Let the alcohol fully evaporate before reinserting. The old habit of blowing into a cartridge is folklore: the moisture in breath causes slow corrosion of the contacts over time, and any improvement you felt came from the act of re-seating the cart, not from the breath itself. Nintendo eventually updated its own troubleshooting guidance to say explicitly: do not blow into your Game Paks.

What to Watch Out For
Before buying, these are the points worth knowing — from someone who handles original Japanese Life Force copies regularly.
Will this Japanese Famicom cartridge work on a North American Nintendo Entertainment System (NES)?
No, not without an adapter. The Famicom uses a 60-pin edge connector while the NES uses a 72-pin connector with a physically different form factor — the two are incompatible at the cartridge slot level. Third-party adapters exist that bridge the pin difference and allow Famicom cartridges to run in a NES. On a Japanese Famicom, NES cartridges face the same incompatibility in reverse. To play Japanese Famicom software, you need a Japanese Famicom, a Famicom-compatible clone console, or a NES fitted with an appropriate adapter.
How should I clean a Famicom cartridge to ensure reliable play?
Apply 90% or higher isopropyl alcohol to a cotton swab and gently wipe the gold-plated PCB edge contacts on the base of the cartridge. Never blow into the cartridge — breath moisture accelerates contact corrosion over time. If cleaning is needed inside, Famicom cartridges use 3.8mm security game bit screws (not standard Phillips); a security bit screwdriver is required to open the shell without damage. Note that most Famicom boot failures originate in the 60-pin console slot rather than the cartridge itself — cleaning the console slot contacts separately with a contact cleaning tool is often the more effective fix.
Before You Buy
Things worth knowing before you buy Life Force
A short checklist for buying a used Famicom cartridge wisely — useful with any seller, anywhere.
-
Choose a seller who tests it before shipping
A copy that has actually been powered on and checked is a known quantity. An untested one is a gamble you only settle after it arrives.
Look for a seller who states it was function-tested and says what they confirmed. A serious seller can tell you exactly what was checked.
-
Make sure it fits your console
This is a Japanese Famicom cartridge with a 60-pin connector; a North American NES uses a 72-pin slot, so it will not fit directly.
Play it on a matching Japanese console or a region-free system, and confirm the listing states the region.
-
If this title saves your progress, check the battery
Cartridges that save use a small coin-cell battery that fades over decades — a dead one wipes your save without warning.
Ask the seller whether the save function was tested. Replacing the battery is possible, but doing so erases any existing save.
-
Check that the contacts are clean
Dirty edge contacts are the most common cause of startup and sound trouble in cartridges of this age.
Choose a seller who cleans the contacts before shipping. A note that it was tested and cleaned means the basics were handled.
-
Confirm it is genuine, not a reproduction
Sought-after titles are targets for reproduction boards with replacement labels.
Ask for a photo of the circuit board and look for factory markings. Favour a shop with a licensed second-hand dealer permit (古物商) — by law its stock has a traceable origin, your simplest guard against fakes.
-
Read the seller's reviews and return policy
A 100% positive record across thousands of sales is close to a guarantee — packing, communication and problem-solving all work for everyone. A return policy protects you if something is off.
Read the feedback and confirm a clear return window before you buy.
The last step before buying anywhere is knowing what it's worth.
