User blog comment:CzrsiNk/Crawmerax bizarre glitch (new 'bunker' on map)/@comment-2125714-20100614145644

Just the plain concrete texture (with the random cracks), nothing flash - but at the back it was dark grey, almost charcoal - in fairness it was probably 'untextured to have that effect.

How bizarre that it stuck it exactly where Craw spawns though - right in that middle spot in-between the rocks.
