Continuing on with the tradition of basing entire story campaigns on previous boss battles, Shovel Knight's upcoming campaign Specter of Torment will be giving the spotlight to the rather ominous Specter Knight. But unlike the previously released Plague of Shadows, the Specter of Torment campaign seems to feature a heavily redesigned version of both the game world and the bosses!
If you're wondering what all of this might look like, here's the recently posted and surprisingly elegant trailer. Its not very long, totaling at around two minutes, but it does offer an excellent glimpse of what Specter Knight is truly capable of. Have a look:
On the other hand, if you're interested in a more detailed look at Specter Knight and his abilities, I would recommend you head over to the official blog. Some of this information is a couple of months old at this point, so don't take it at face value, but it is still the most detailed description of Specter Knight's move-set I could find.
As for the release date, you can expect to see Specter of Torment at some point this spring, though the exact date hasn't been given just yet. But on the positive side, the entire update is going to be completely free! You really have to hand it to the developers, they sure are dedicated towards making Shovel Knight the best game it could possibly be, even if it takes them actual years to do so!
