It's been several months since we've last heard about Ready or Not, the ambitious Rainbow Six-like shooter from developer Void Interactive. Despite this lengthy silence, the studio assures that development is progressing steadily, and now it has shared some more progress details about the game.

Like the Rainbow Six and SWAT series, Ready or Not is a tactical police shooter that puts players in the role of an "elite SWAT team tasked with defusing hostile situations in intense, claustrophobic environments." Void hopes to set it apart from similar titles with its emphasis on realism, which extends to all facets of the game, particularly its animation and AI.
