Under Night In-Birth 2 Sys:Celes Review: A Deep Dive into the Ultimate 2D Fighter
The Ultimate 2D Fighter?
You might be thinking, "Another fighting game review? In 2026?" Well, yes, but hear me out. Under Night In-Birth 2 Sys:Celes is a fighting game that came out in 2024, building on the foundation of its 2012 predecessor. And it's a game that truly shines for fighting game enthusiasts who crave the fast-paced anime fighters of old, but with all the modern conveniences we've come to expect. It's a game that's both incredibly deep and incredibly rewarding, and it's one of the best 2D fighters on the market right now.
A Unique Fighting System
At its core, Under Night In-Birth 2 Sys:Celes features a unique fighting system that breaks free from the linear combo logic found in most fighting games. Instead, it encourages you to experiment and chain heavies into lights and lights into heavies, or convert big combos off of little pokes. This freedom is liberating, allowing you to land big damage from any touch, making the game accessible to beginners while still offering a satisfying challenge.
Intuitive Character Control
Despite the complexity of the fighting system, the game makes it easy to jump into a new character. The flexible nature of the system means you can play casually without relying solely on auto-combos, making it a great choice for those who want to experiment with different characters.
GRD System: A Tug-of-War Mini-Game
But don't let the accessibility fool you. Under Night In-Birth 2 Sys:Celes also introduces the GRD system, a unique mechanic that adds a layer of complexity. It's like a tug-of-war mini-game that runs parallel to the actual fighting. You fill your side of the meter by moving forward, landing attacks, blocking, using shield blocks, and holding down the Exs Action button. The person with the most filled meter wins the mini-game and enters the Vorpal State, gaining a damage boost and the ability to use Chain Shift.
GRD: Brilliant and Complicated
The GRD system is brilliant because it encourages aggressive play while rewarding skillful defense. It's largely negligible at lower levels, but skilled fighters must split their focus between attacking and managing the GRD meter. This mechanic further encourages careful meter and resource management, a key aspect of modern fighting games.
Stunning Visuals and Characters
Arc System Works has done an incredible job of blending 3D characters in 2D environments, but Under Night In-Birth 2 Sys:Celes also excels in 2D sprite art. The characters are absolutely brimming with personality and flair, from Minerva's wild flowing hair to Seth's lightning-fast speed and Waldstein's hilariously gargantuan arms. The 24 characters (plus three more as paid DLC) are a joy to play as and against.
Rushdown Mastery
I'm a big fan of rushdown characters, and Linne is a prime example. Her incredible run speed allows her to close the distance from full screen in a blink, making it fun to find openings and blitz opponents with basic strikes and throws. The game's teaching tools are stellar, offering a mission mode that covers a wide variety of combos and situations, helping you build a full game plan for each character.
Story Mode: A Mountain of Jargon
Unfortunately, the story mode can be overwhelming for newcomers. It's filled with jargon and names that only make sense if you've played the previous games in the series. The world and lore of Under Night are extensive, and the story mode lacks context, making it difficult to follow without prior knowledge.
Replay Takeover: Learning from Mistakes
Under Night In-Birth 2 Sys:Celes offers a unique feature called Replay Takeover, allowing you to take control of a character during a replay. This is a godsend for improving your matchup knowledge, as you can analyze and learn from your mistakes, finding ways to counter your opponent's offensive sequences.
Verdict: A Must-Play for 2D Fighter Fans
Under Night In-Birth 2 Sys:Celes is a must-play for fighting game enthusiasts. It's incredibly deep, features a rich and well-rounded roster, and provides excellent teaching tools. The Replay Takeover feature is a game-changer for those who want to truly master the game. While the story mode may leave newcomers feeling lost, the game's core mechanics and features make it one of the best 2D fighters on the market.
