Nen Fighting Simulator is a Roblox game built around the Nen system from Hunter x Hunter. You train, unlock Nen types, and fight your way up through a power-based progression system. If you’re a fan of the anime, you’ll recognize a lot here. If you’re not, it’s still basically a solid anime fighting grinder.
What You Actually Do in the Game
You start out weak, like genuinely weak. The early game is all about grinding stats by training your body, building up your aura, and eventually awakening your Nen type. There are four main Nen types you can unlock, including Enhancer, Transmuter, Emitter, and Conjurer, and each one plays a bit differently.
Once your Nen is awakened, you start learning abilities tied to your type. Enhancers get raw power boosts, Transmuters can shape their aura in unique ways, and so on. Fighting other players and NPCs is how you level up fast and test out what you’ve unlocked. There are also boss-type enemies scattered around that drop better rewards.
The map has different zones you unlock as your power level climbs. You can’t just rush to the end area early, the game actually gates you behind stat requirements. It keeps things somewhat structured instead of just letting everyone chaos-run the whole map from minute one.
The Good Stuff and the Frustrating Parts
The Nen type system is genuinely cool if you’re into Hunter x Hunter. Seeing your character build out abilities that match the anime feels rewarding. The combat has some depth to it too, it’s not just spamming one button and hoping for the best.
That said, the grind is brutal. Early training takes forever, and if you don’t have a gamepass or some kind of boost, it can feel like you’re just clicking the same thing for an hour to see minimal progress. The game also has some balancing issues where certain Nen types feel noticeably stronger in PvP, which gets annoying fast if you picked the “wrong” one without knowing.
Player count has dropped from its peak, so finding active servers with other real players can be hit or miss depending on when you log in. The developer has pushed updates before, so it’s not completely abandoned, but don’t expect the same energy it had closer to launch. It’s still worth trying, especially if you’re into the anime, just go in knowing the grind is real.
