One of the most mechanically layered 2D fighters in years, UNI2 rewards patient players willing to wrestle with its GRD system - casual button-mashers will bounce off fast, but committed players will find something genuinely special.

My first honest reaction to UNDER NIGHT IN-BIRTH II Sys:Celes was confusion, followed shortly by reluctant respect. The name alone should warn you: this is not a franchise chasing mainstream approval, and the game backs that up at every turn. Developed by French-Bread and published by Arc System Works, UNI2 is a 2D anime fighter that launched in January 2024 into one of the most crowded fighting game periods in recent memory, competing against Tekken 8, Street Fighter 6, and Granblue Fantasy Versus: Rising all in the same window. The fact that it holds its own says something real about the quality of its core design. The heart of everything here is the GRD (Grind Grid) system, a shared meter at the bottom of the screen that shifts based on how well both players are performing - landing hits, blocking, moving forward, or holding a dedicated charge input all push it your way, while getting hit or retreating drain it. When a periodic timer expires, whoever holds the majority of GRD enters Vorpal state, gaining a damage boost and unlocking additional special actions. UNI2 tightens that timer to around 14 seconds and layers on two new mechanics: Creeping Edge, a risk-reward dodge that costs GRD, and Celestial Vorpal, which triggers if you win a Vorpal cycle with six or more blocks filled, fully maxing your gauge and turning you into a genuinely frightening force for the remainder of that sequence. This last mechanic functions almost like an unofficial round-ender when it fires - the pressure to manage your GRD intelligently rather than just throwing out combos is what separates UNI2 from most of its genre peers. Every match becomes a tug-of-war that you are always playing on two levels simultaneously. The roster ships with 24 characters, including three newcomers. Tsurugi is a shield-wielder whose stance system branches into a huge variety of follow-up options, making him complex to pilot but enormously frustrating to read as an opponent. Kaguya is a dual-pistol huntress whose projectile zoning fits players who want range and mobility. Kuon, the story's antagonist, plays like a more melee-focused take on the existing charge character Vatista, which makes him approachable for rush-down players who already understand space control. Every existing character also received new moves - Hyde gets Blaring Outrage, Linne gets Soaring Dragon - so returning players have fresh tools to learn across the whole cast. An auto-combo system and one of the most extensive tutorials in the genre help newcomers get moving, but the honest ceiling here is very high, and the online player pool skews toward veterans who have been playing this series for years. Jumping into ranked cold as a new player is a rough experience. On the content side, UNI2 keeps things lean. Story is delivered through per-character arcade ladder runs - brief dialogue snippets before and after specific matches - which wraps up the Hollow Night saga but drops the dedicated visual novel chronicle mode from the previous release. Fans invested in the lore will find some satisfying conclusions; everyone else will skim it and head back to training mode. The offline single-player options are genuinely sparse when stacked against contemporaries like Street Fighter 6 or Tekken 8, and that comparison hurts. The PC port at launch had a handful of reported quirks including resolution-change freezes and occasional menu crashes, though actual gameplay in matches remained solid. Steam user reviews sit at Very Positive overall, which tracks - the combat is good enough that players forgive the thin surrounding package. Who is this for? Fighting game players who already know footsies, GRD concepts, and want a system that demands attention on every single input. Players drawn to gorgeous high-resolution sprite work in the Guilty Gear or BlazBlue tradition. Anyone who played the original UNI and wanted rollback netcode and a cleaner, higher-stakes version of the GRD loop. If you are coming in completely cold hoping for a Mortal Kombat-style cinematic story mode and a deep solo content well, you will be disappointed. The bones here are exceptional; the house built around them is small. Alex, Scout Team
