Triptych is a Lovecraftian horror adventure written and developed by Dark Craft Studios. It deals with two brother's journey into the occult, Necromancy, and cosmic horror.
Triptych as well as Worry of Newport are some of the best mods available for Crysis. The voice acting is great for mod standards and the writing is decent enough to keep you going. Best part of the mod is the atmosphere and detail put into the environments-- great work has been done with the Crysis assets and it's almost unrecognizable from the vanilla game. The only real negatives I have is that the invisible walls are a bit in your face sometimes and some cutscenes drag on (although they're beautiful at least). Other than that it's a must-have for Lovecraft or horror fans.
