Congestion 1024 is a Doom II megaWAD released in 2005, born from the Exquisite Corpse project, in which a collection of mappers created twelve 1024 x 1024 maps and bound them together as a single, contiguous level. I assume either those involved or those observing found the individual puzzle pieces so intriguing that they made an entire WAD out of similarly sized bits, creating 32 levels of intense action. The rules: the player is bound to a 1024 x 1024 area. They are allowed egress as long as they die upon leaving the 1024 confinement. Monsters, of course, are allowed to be outside the area's bounds and frequently are.
