Special Operations: Killzone 3.0. This is a very Necromunda-like fan variant of regular 40k. It provides quick, fast-paced games with a small amount of models. The rules can be downloaded at the link above.
I brought mostly what I had painted; two thunder hammer terminators, one tactical marine, and the rest were scouts, including a sergeant. The rules provide that one model be the 'leader' of the kill team. My leader was my terminator sergeant. In all I think I had about 10 models.
