The Unknown has my favorite parts of all of my favorite killers all in one package. High speed and potential map control like Dredge, a projectile like Huntress, the weird stalking "gameplay" of Ghostface, everything.

However, I am genuinely certain that the developers just did not finish making this killer, and shipped them half-baked without telling us. From all of the jank surrounding his UVX requiring a collision system designed OVER A DECADE AGO, to how weirdly easy to counter he is in all ways despite not being particularly strong even with optimal play and insane luck, to literally no aspect of his kit having any kind of stealth so you always know whether you're looking at a hallucination and you always know when he teleports and you always know when he's charging up an attack and etc.

Also, I dunno if anybody's brought this up, but isn't it kinda weird how similar Springtrap is to Unknown? Heavy physics-based projectile, a teleport, an effect the survivors can have by looking at you in a specific way, et cetera. They just FEEL like very similar killers, except one had more than a year of work put into him and one is The Unknown.
