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 is the ever-so-deadly Chimera... well, formerly ever-so-deadly. It was getting all attack-ey and I had to shoot it a few times.

Should provide a nice challenge.
