The most visible impact of version 1.45 was the expansion of the roster, most notably with the inclusion of Ushiwakamaru and The Count of Monte Cristo from the Fate/Grand Order universe. While guest characters can sometimes feel disjointed, these additions were integrated with the mechanical depth expected of a Melty Blood title. Ushiwakamaru brought a high-mobility, aerial-focused playstyle that challenged the existing neutral game, while the Count of Monte Cristo introduced complex pressure sequences and unique visual flair. These characters did more than just pad the numbers; they broadened the game's appeal to the massive Fate fanbase while providing veteran players with entirely new archetypes to master.

Before this patch, the game reached its current full roster through several free DLC drops:

For players, v1.45 represents a "frozen meta" – a perfectly imperfect fighting game that rewards fundamentals, creativity, and a little bit of Type-Moon chaos.

This was a more subtle but critical change. In v1.44, players could input a throw while air blocking to automatically tech throws or throw the opponent on landing. Now, if you air block, you must manually time your throw tech or punish, adding a layer of risk to jump-ins.
