A week removed from Summer Game Fest, one of the demos I can't stop thinking about is Onimusha: Way of the Sword. The behind-closed-doors demo was different from the one that's available on Steam—it took place slightly later in the game and showed off one of the game's "open areas" within Kyoto.
Several things stand out in Onimusha: The art, the methodical movement, the sword-wielding zombies, but most of all, it was the swordplay. For all of the comparisons to Sekiro that this reboot is likely to receive, let it be known its melee combat is in another league.
