Different masks = secret cutscenes?
Well, no, not reallly, of course not. Nothing game-changing atleast. However, recently I encountered one instance of this phenomenon.
I played through the level "Tension", while wearing the Dennis (wolf) mask. In the following cutscene at the grocery store, a tracksuit-clad man wearing the Dennis mask appeared, standing against the wall of the store, cornered by gangsters. I couldn't interact with them in any way, so I just went ahead and talked to Beard. After he was done talking, I grabbed the bag off the shelf and headed for the car. Meanwhile, the goons disappeared and all that was left of the scene outside was the corpse of the mask wearing man.
I repeated the level with a different mask, thinking it was just something added in a new patch I missed (something like "Highball"), but it turned out I could only access that part of the cutscene if I passed the level with the wolf mask.
I started wondering if there are any more of these "secret" scenes in-game and I figured it'd be faster to ask here, than replay each level 26 times, wearing different masks. So, if you ever happened to come across something like that, drop a comment below, if you please.
(also, Jones doesn't count, since there's an achievement for him and all)
