Sixty pages of human free will at its zenith.
Whereas the first half of CREAMINT was entirely world building and established the flavor of the Delta Cream universe, CREAMINT 2: Secret Sauce is dense with mechanics for use at the table. The lore of Delta Cream expands piece by awful piece in these mechanics, revealing a sprawling, ill-managed, and desperate splinter of Delta Green which could either disintegrate or fracture away at any moment. Delta Cream is spread far too thin for the horrors it is tasked with facing, and its members uniquely traumatized by the nature of their mission.
The Special Rules are built off of preexisting rules within Delta Green rather than an attempt to create more game from scratch. This is a remarkable demonstration of restraint and, in my opinion, the right decision to keep Special Rules easily modular. Doing so helps to preserve the Delta Green tone at the table we all know, fear, and love, and won't stray games too far from the original balance, either.
Much of the material in CREAMINT 2: Secret Sauce can be transposed into any "vanilla" Delta Green game with little to no modification should one, for whatever reason, find the Cream Theme distasteful. This is worth taking a look at for the poison stat blocks alone.
Also, the artwork is absolutely charming.
