it is a new classic themed map with various (and weird) secrets.
It is fairly long (and become way longer if try the secrets) and feels like an actual classic map (don't bet that heavily on the secrets).
It also has normal and classic difficulty. On normal if you die you respawn (no limits) in classic after first death you get game over.
And finally some monsters drop weapons after you kill them (not many depending on demon type) and drop specific ammo after you perform glory kill (depending on demon type).
P.S.: no double jump or grab ledge (you don't need them don't worry)
