HoloCure - Save the Fans! is a free, fan-made roguelite developed by Kay Yu and inspired by the talents and universe of Hololive. At first glance, the concept sounds almost impossibly niche: choose a Hololive character, fight enormous waves of enemies, collect experience, build increasingly ridiculous weapon combinations, and try to survive long enough to defeat increasingly powerful bosses.
In practice, it is an exceptionally polished take on the survivor-like formula.
Each playable character has their own unique starting weapon, special ability, stats, and upgrade possibilities. As enemies flood the screen, defeated opponents drop experience that allows you to level up and choose new weapons or upgrades. Weapons can be combined and evolved into more powerful forms, while character-specific abilities encourage different approaches to building your run.
The fun comes from discovering how all of these systems interact. One run might focus on overwhelming the screen with projectiles, while another turns your character into a close-range damage machine or builds around defensive effects and healing. Once you understand the game's systems, you start experimenting with combinations simply because you want to see how ridiculous they can become.
And HoloCure is far more than a basic survivor-like.
Outside of the main stages is an extensive progression system that gives you reasons to keep playing after a run ends. You can unlock characters, weapons, upgrades, costumes, achievements, and other content while gradually building up your account. There are also fishing, farming, cooking, an arcade, a management-style mode, and other side activities that make the game feel surprisingly substantial.
The presentation is another major strength. HoloCure uses charming pixel art and animations that are packed with references to Hololive personalities, memes, jokes, and fan culture. The game constantly rewards players who recognize those references, but you don't need to be deeply familiar with Hololive to understand the basic gameplay.
Most importantly, it is completely free. There is no premium currency, no gameplay locked behind a payment, and no requirement to spend money to access the core experience. This is a fan project made with an almost absurd level of care.
That makes HoloCure particularly interesting to us. It's a reminder that some of the best free games aren't trying to compete with AAA releases. Sometimes they're passion projects built by people who simply love a particular community, genre, or idea enough to make something far bigger than anyone expected.
HoloCure is the gold standard for fan-made passion projects. Kay Yu took the Vampire Survivors formula and elevated every piece: 47 distinct characters with bespoke weapons, creative super-collab fusions, an entire secondary life-sim in Holo House, and an uncompromising commitment to 100% free gameplay with zero microtransactions or ads.
