Gradius: its lineage, descendants, and standing in Japan
01What this origin is
Gradius is a horizontally scrolling shoot 'em up developed and published by Konami, released in Japanese arcades in May 1985 (and internationally as Nemesis). Rather than have the player's ship pick up isolated power-up items, it introduced the 'power meter': collecting capsules advances a highlighted option along a row of upgrades at the bottom of the screen, and pressing the power-up button locks in whichever option is currently lit, an idea the development team modeled on a keyboard's function keys so players could choose their own build on the fly instead of having it chosen for them. Widely credited alongside Namco's Xevious as one of the shooters that defined the genre, it is the origin of a lineage of shoot 'em ups that hand the player a menu of upgrades to spend deliberately rather than collect automatically.

Crimzon Clover World EXplosion Buried gem
A vertically scrolling bullet-hell shooter built entirely around point-blank risk: fly close enough to an enemy and you gain energy faster, lock on faster, and deal more damage, the same proximity that could get you killed. Holding the lock-on button paints a target line across everything in range, up to 24 enemies at once (28 in Break Mode, 32 in Double Break), and releasing it fires a spread of homing lasers whose count feeds a score chain multiplier. Fill the Break Gauge and Break Mode kicks in, spiking damage, speed, lock-on speed, and the value of the gold stars enemies drop; keep it full and Double Break stacks on top, adding an extra Option pod and doubling the bonus again. The new ARRANGE mode reworks that same escalation into a build you choose yourself: picking up score items charges a shared multi-gauge you can spend at any moment on support pods, speed-ups, and other power-ups, rather than have them assigned to you automatically. Three difficulty tiers, NOVICE, ARCADE, and ARRANGE, each branch into several modes of their own. Developed by the Japanese doujin circle Yotsubane, also known by its circle name CLOVER-TAC, which first showed the game at Comiket 79 in December 2010 before releasing it for Windows in January 2011; Adventure Planning Service, a Tokyo studio founded in 1987, joined as co-developer from the Nintendo Switch version onward. Published by KOMODO, a small Tokyo-based label spun out of Degica Games' game division in 2021. The previous Steam version, World Ignition, was discontinued at the publisher's request in December 2021, the same window in which this successor, World EXplosion (first released on Switch in October 2020), arrived on Steam on December 6, 2021. It is Very Positive at 96 percent per Steam's own store page (364 of 376 reviews positive per Steam's review API). It supports English, French, Italian, German, Spanish, Portuguese, Polish, Japanese, Simplified Chinese, and Traditional Chinese, yet only about 273 of those 376 reviews, roughly 72.6 percent, are in English so far. PC Gamer has already run a feature on it, 'Revisiting Crimzon Clover, a shmup that rivals the genre's best,' and both Nintendo Life and the community reference wiki shmups.wiki have covered it, so calling it a game the West has never touched would not be honest; what is true is that its recognition still sits mostly with the core bullet-hell audience, and it has yet to reach a wider, non-shooter crowd. It is a paid title at ¥1,980 in Japan ($19.99), not free, fully launched and not in Early Access, with no AI-generated assets and, per Steam's own content descriptors, nothing sexual (ids: none, notes: none).
