Being a R-Rated expansion to Batman: Under the Red Hood, and an interactive one no less, this is bound to have its moments of terror.
WARNING: Spoilers are unmarked.
- Jason meeting Talia and being stunned to learn that she gave birth to Damian, then agreeing to work with Talia for Damian's sake while he mentally monologues about how he's going to turn Damian against his own parents as part of his quest for vengeance against Bruce.
- Jason walking into a diner and having a friendly chat with a man who seems to know how Batman works. Then the man tells him a haunting story about two Arkham Asylum inmates, and as he goes on, Jason recognizes it as the same "killing joke" the Joker told Batman the night he shot Barbara. Cue the camera finally showing us the face of this mysterious man and - Jason shoving a knife into his eye.
- Just right before, you get a good long shot of the man's face. The comically wide eyes, the wide inhuman grin...that sure as hell is the Joker, showing off one of his creepiest smiles yet. And once he gets stabbed in the eye, he just laughs off all the pain knowing that Jason's been had by his parting joke, dying with a relaxed grin, with a somber piano in the background.
- One ending has Jason as the Red Hood facing down a revived and broken Batman acting as "the Batman of Zur-En-Arrh", presented by Talia al Ghul. A short Single-Stroke Battle occurs before a dying Batman reveals he had a bomb, which kills the three of them. The last scene is of close-ups on all three of their charred, ravaged corpses. The sheer, visceral detail just makes it ten times worse.
- The implication that Talia raped Batman of Zur-En-Arrh, claiming he spoke "with his body" despite his limited speech capacity and clear mental problems. Jason looks disgusted and voices how horrified he is that Talia basically sexually violated his surrogate father.
- Black Mask's brief appearance during Red Robin's bloody crusade ends with his head being decapitated with a blown-off door. If that weren't enough, we get to see his head begin to melt from said door's flames.
- Really, Black Mask is almost a Happy Tree Friends character given how whenever he does appear, it's to be killed in an over-the-top but nonetheless horrific way. In the "Robin Lives" route he'll be sliced in half by shattering glass. And in the Hush route, he's blown up by a rocket launcher and you see him screaming while burning as he's flung into the air by the explosion before he lands on a fuel truck, which explodes.
