The Combustible Map Pack is a map pack released by Epic Games as the second downloadable content pack for Gears of War 2 (if the Flashback Map Pack is counted). It is currently priced at 400 Microsoft Points. It contains the maps Flood, Gold Rush, and Fuel Station. The maps are based around things that either blow up or that burn you. In Flood, the level of Imulsion rises over time, and in Fuel Station there are many places that can be shot to create an explosion. Gold Rush doesn't seem to have anything actually combustible in it, but seems to put a little bit more of an emphasis on explosive weaponry.
