Nephenthesys Switch NSP Free Download Romslab I vividly remember an older issue of Electronic Gaming Monthly showcasing the shortest reviews ever written in the history of the magazine, with one of them just reading “this is just another martial arts game”. I honestly feel like could have been able to review Nephenthesys by just saying it’s just another bullet hell shooter, and it wouldn’t have been considered lazy writing. This game is just that, yet another bullet hell shooter. You control a starship, and you need to destroy everything in front of you, all while avoiding an onslaught of laser shots and missiles.

At the end of the the stage, a boss fight will test your shooting and dodging skills. Rinse and repeat until you’re done. The difficulty level is one of the more noteworthy aspects as Nephenthesys presents a tough but fair challenge. It’s quite a methodical example of the genre, with enemies swarming the screen in Galaga-style waves, either firing slow homing shots indicated in pink, or blue shots on a fixed trajectory. Over time you’ll easily be able to predict patterns, and there’s nothing here too overwhelming. It also helps that the crafts are speedy enough to dart around incoming fire.
Navigate caverns, waterways, cityscapes and other unique environments.
Take down a larger enemy, or enemies highlighted in yellow – which often appear at the end of a wave – and a power-up will appear. These haphazardly bounce around the screen for around ten seconds. When a lot of projectiles are in motion, nabbing one can be tough – which adds an extra layer of skill to manoeuvring. Some power-ups will replenish health, while others boost firepower. Only when health is full can a smart bomb be activated – an odd choice, considering most players will be accustomed to relying on smart bombs to escape death.

The first thing to do will be to select your ship since this will establish what your main weapon will be, as well as what your drone will do. Red Flash is a red spaceship equipped with a heavy machine gun as its main weapon and a smart bomb for its drone. As expected, Blue Sting has a laser beam for its main weapon and will have a hyper laser for its drone. Green Dragon uses as scatter gun and has a drone with a tornado bounce. Yellow Wasp has a powerful phase cannon and a heavy shield for its drone.
Experience old-school shoot’em up action inspired by arcade genre classics!
There are five extra ships for you to unlock, so there’s some replay value here if you’re the type of gamer who likes to 100% games. To be able to use them, you’ll need to complete specific objectives. These are completing the game with any ship, scoring 40,000 points during the game, finishing any stage without taking damage and without using drone powers, finishing Stage 3 with the Purple Needle ship, and finishing Stage 2 with the White Prism.

All while facing an onslaught of extraterrestrial adversaries that will test even the most experienced player’s skills and determination. In Nephenthesys, collecting power-ups will help to enhance your firepower with wider shot spreads and unleash special bombs to turn the tide. Again, it’s not like this game is poorly made. It might have repetitive visuals and an atrocious soundtrack (it does sound like a subpar game from the TurboGrafx-16 at best), but it controls fine enough. It’s really hard, borderline impossible even, to ruin the control scheme and responsiveness of a bullet hell shooter
I don’t know if that is a boss or a logo for a black metal band.
So I’m glad Nephenthesys does the bare minimum and feature great controls and a steady framerate. It also features a selection of different ships to control, each one with a specific secondary shot, which takes away one chunk of your energy meter. For instance, one of the ships might use this shot to unleash a screen-clearing bomb attack. This might be the closest this game might feature as “innovation”, as your health, shot strength and amount of ultimate attacks you can unleash are all tied to the same energy meter. Besides this one little detail, you’ve played hundreds of similar games like Nephenthesys in the past.

With all these old skool sensibilities in play – especially the fact that just three continues are granted – you may be surprised to learn that Nephenthesys features 3D visuals, both for backdrops and enemies. The majority of enemies have a spindly, skeletal, look, helping to induce personality, and the bosses are varied, ranging from supersized UFOs to mechanical octopi. Their health bars take a while to whittle down, and attack patterns are altered once the bar is halfway depleted, sometimes catching you off-guard. ATOM RPG Switch NSP
