Visually, the game isn't bad at all, especially seeing as it is on the only previous-gen system that is still going strong. Both character models (human and mutant) and the locations around the University look good and fairly smooth. The only real problem I had with the game's look is the excessive darkness. Since the game is based off of stereotypical horror movies, I can see how they were trying really hard to go for the cheesy jump scares, and you need darkness to pull that off, but there were too many times when I found the game really hard to see. So if you're going to play Obscure: The Aftermath, you will have to either turn up the brightness of your TV, or turn down the ambient lights. Of course, turning off the lights might be just what the developers want in order to help set the mood.
Now for the dialogue - I really can't believe how cheesy it is in parts. There were several occasions where I just didn't like how the characters interacted with each other. I'm going to give the writers the benefit of the doubt though and say that the excessive and obviously bad dialogue is because the game is trying to be reminiscent of the equally bad horror films it is inspired by.
