Technically speaking, it's not strictly accurate to call Judas and BioShock 4 competitors. Judas developer Ghost Story Games is a subsidiary of Take-Two Interactive, while BioShock 4 developer Cloud Chamber is a division of 2K, another Take-Two company. Still, these games are very similar, so it's only natural that some people will want to compare the two. Thus, even if Judas and BioShock 4 aren't technically rivals, it's hard to talk about one without at least thinking about the other.
