The original Spelunky first arrived on consoles in 2012, and it became a near-instant hit with both the roguelike and co-op communities.  The punishing platformer then made the rounds to a few other platforms, including the PlayStation 4 in 2014.  After that, though, we saw very little from creator Derek Yu outside of hints and teases at a possible sequel.  Information began to intensify about Spelunky 2 over the past couple years, culminating in Sony's most recent "State of Play" livestream, which heralded a PlayStation 4 release date with the below trailer.

Details on specific mechanics (and a release date) remain scant, but we were fortunate enough to see multiple new screen shots of the game in action.

One of the first new features fans of the first game may notice is the liquid physics that result in a bunch of lava getting dropped on poor Ana's head. Those physics mean that if you cause any kind of liquid to leave its confines, it will follow a path until it finds a new receptacle or reaches the bottom of the level, which could make things even harder for you. The other new feature that we see amidst the reveal of online co-op (!) is the concept of layered levels. Basically, in every level, there will be a door (either hidden or in plain sight) that will take you to a new layer with a different layout than the previous one. In the video (right around the 0:40), this is shown as players first being in a kind of underground looking place, and then in a more jungle environment. I'm sure there are other little things that Spelunky enthusiasts will glom onto in all of this, but I'm just excited to be able to team up with friends online now!
