A set of small, piecemeal mods for various aspects of S.T.A.L.K.E.R.: Clear Sky. Stash Auto-Filler, modifiable "Trophy" AK-47/2, cut content restoration (including cut monsters/mutants) and others, all available as individual packages for each change.
Here's one of the cut enemies brought back by the Forgotten Fiends Micro-Mod: the classic Zombie. One of seven variants, I should say. This is one of the weaker types, using a texture that wasn't fully integrated with its own model (and thus rarely seen in other mods that bring Zombies back).
