Slitterhead is the first title from Bokeh Game Studio, founded by Keiichiro Toyama's silent Hill SY Siren fame. In it you play as disembodied spirits who can bond with powerful characters known as Rarities. You go on a linear-ish mission in an 80's Asian city, controlling Rarities to take down Slitterheads and figure out what's going on in the jumping narrative.

That's why Slitterhead It's mostly a linear experience with mission-based progression, there's not much free time to spend gallivanting or completing side quests or anything like that, so most players should take the same amount of time seeing the end credits. Slitterhead the player should be able to complete the game approx 15 hours, more or less.
At that time we managed to get 70% of the achievements, and for those which aims to gain SlitterheadThe Platinum trophy (or any Steam/Xbox achievement) should get you therein about 20 hours.
The achievements that may take the longest to complete are the difficulty ones, where you have to clear the game in the hardest way, and those where you have to collect all the accessories/clothes for the Rarities.
Finding the collectibles in each mission is harder than it looks, as there are no directions or in-game maps to find their locations, so you'll spend a lot of time running around Kowlong.
