ConC.E.R.Ned (or ConCERNed) is a July 2013 megawad for Doom containing 27 levels, replacing the first three episodes. It was created by Matt Powell (cannonball). The plot occurs at a futuristic version of the CERN Large Hadron Collider.

Powell subsequently created the Return to Hadron series of episode replacements that are based on the ConC.E.R.Ned levels to some extent.[1] In addition, his episode 4 replacement called Thy Flesh turned into a draft-excluder is sometimes considered a sequel.
