There are two map files included here: dm_lukovich.bsp, and dm_lukovich_nocc.bsp.

dm_lukovich.bsp is the map with the original, intended MGS3-style piss filter.

dm_lukovich_nocc.bsp is a version of the map with no color correction for those of you
who don't want a piss filter, which is likely most people.

Have fun, and happy sneaking!
