"Batman: Arkham Knight" will be the last of Arkham games Rocksteady will be doing, which is the reason why there is no secret room, GameSpot learned.

Game director Sefton Hill responded to a fan inquiry on Twitter with, "There's no hidden room revealing the next game as it's our last Arkham game. Sorry if you've been looking."

"Batman: Arkham Asylum" and "Batman: Arkham City" had one and it usually teases about Rocksteady's future Arkham games, so it's expected that gamers would be looking for one in "Batman: Arkham Knight," according to TechTimes. Nonetheless, the developers are making the most out of it by releasing DLCs, and here's a sneak peek of the character selection for AR challenge that will be coming this October.

Hill also teased about the Predator maps that will be coming to "Batman: Arkham Knight" this November.

October, though, is quite a bit too long for the "Batman: Arkham Knight" gamers, so here's something that will be coming out in Sept. 22.

Of course, do not forget the "Batman: Arkham Knight" Crime Fighter Challenge Pack # 2, which will be released on Sept. 29.

"Batman: Arkham Knight" was released on June 23. The PS4 and Xbox versions were reportedly amazing, but the PC version had issues. A few months later an interim patch was released, but it's still not available in PC.
