60. Ufouria: the Saga (Sunsoft, 1991 in Japan, 1992 in Europe/Australia)
Another great homeport of a kickass Konami arcade game never got released elsewhere. But at least I have an answer for why it didn't in this case; on the Famicom, this game's cartridge utilized a custom memory mapper, and it would be a lot of effort to covert it over to NES hardware, and since the original game wasn't especially popular overseas they decided it wasn't worth the effort. Those who got to play it were in for a treat, though, as it was another great game in the series. Now employing vertical scrolling as well as horizontal, as well as plenty of crazy stages where you're travelling between suns battling giant dragons and other crazy eye-popping sights. As per series norm, it is also an exceptionally tough experience, requiring much practice and impeccable power-up usage if you want any hope of seeing your way to the end.
58. Super C (Konami, 1990)
57. Summer Carnival '92: Recca (Naxatsoft, 1992)
Recca is a game known for three things: Giving the Genesis's Blast Processing a run for its money with the fluidity in its gameplay and animations, being extremely rare (only seeing limited release as part of a Japanese competition) and its monstrous difficulty. From beginning to end this game's action is utterly relentless, with constant swarms of enemy ships and bullets flooding the screen amongst a plethora of flashy visual effects and intense, pulse-pounding music, and it all blazes along at speeds the hardware doesn't even seem like it should be capable of at all! If you want a game that will push your reflexes and shoot-em-up skills to their limits (and if you can find a copy), look no further than Recca, because it is truly one-of-a-kind.
56. Mega Man 6 (Capcom, 1993)

55. Crisis Force (Konami, 1991 in Japan)
The Konami shmup legacy continues, and Crisis Force is arguably one of the best they've ever done. It's a unique one too in terms of design, with a technological ancient Egyptian theme and some huge, detailed sprites every step of the way. Your ship could also transform into three different configurations - one that fires multiple guns forward, one that fires forward and backward and one that fires in three directions simultaneously, allowing you to adapt to your challenges, and one could even collect parts that would combine both players' ships into one large and very powerful one for a short period. Really fun stuff, though it does tend to get laggy when the action gets intense (especially in two-player mode). Unfortunately, being released so late in the system's life also ensured that not too many people played it even in Japan, making it a rare and spendy title nowadays.
Sunsoft was another big name to many NES gamers, creating quite a few high-quality games in their time (including more than a few licensed tie-ins of surprising quality). Blaster Master is one that's fondly remembered by many; known as much for its solid gameplay and design as its silly localization. The Japanese version was a tale about an alien invasion in a distant world while the US version was reworked to be about a kid searching for his pet frog, mutated into giant form by radiation. Either way, though, the game is a solid one, having you control both the protagonist in top-down shooter sections and the tank in side-scrolling ones, defeating bosses and finding numerous upgrades in order to progress. From jet thrusters to driving up walls to upgrading your tank's artillery, it's a game with quite a lot to experience. The only downside was a lack of any kind of save or password feature, so it was a game you had to not only get good at, but beat in one long session!
52. Life Force (Konami, 1988)
Known as "Salamander" in Japan, Life Force is a spinoff of the Gradius franchise, featuring both side-scrolling and top-down scrolling gameplay and a similar power-up system. It definitely plays up the horror influence too, taking place in the body of a giant alien and having appropriately creepy, fleshy environments and bosses to square off against. The NES version, in addition to being heavily reworked from the arcade, was also notable at the time for featuring two-player simultaneous co-op, and surprisingly it shows little slowdown during it even when the action really heats up. But of course, Konami pulls no punches with the difficulty either - if you don't memorize the ins-and-outs of every battle and plan your movements carefully, you're not going to be able to finish this one.
