One of the best throwback games in recent memory is definitely Shovel Knight from developer Yacht Club Games. Last September (it's been that long?), the team dropped the free "Plague of Shadows" expansion for all platforms. This year, we have word of when the next add-on will release. "Specter of Torment" will come out sometime next spring, according to a tweet from Yacht Club. Not much else is known at the moment, but the team did offer a huge update back in June all about new protagonist Specter Knight -- wall climb! Dash slash!
