BlizzCon 2010 has started in Anaheim, California and the StarCraft II section of the show floor is showing off some Blizzard-made custom maps for the hit RTS game that reference other well known games, along with a cult hit cooking TV show.

According to Shacknews, the maps include maps that make references to Valve's zombie shooter Left 4 Dead, PopCap's puzzle game Bejeweled, the hit WarCraft III mod Defense of the Ancients and even the Iron Chef TV show. The StarCraft II section is also showing off the maps made by the winners of the recent custom map contest. During the BlizzCon opening ceremony it was announced that the Blizzard custom maps will be released for free in the coming months.
