" "Big Bang Comics is a superhero role-playing game, written by Chris Carter and published by Pisces All Media in 2006. The game uses a modified version of the d20 System.
Characters in the game exist in either of the two worlds of Big Bang Comics (the Silver Age Earth-A or Golden Age Earth-B). Players may create new heroes or take the part of existing heroes from Big Bang Comics. Characters are created with two character classes: a power origin Entry Class, and a "civilian identity" representing their out-of-costume occupation. The power origin classes include choices such as Mutant, Elite (super-trained normal), Sorcerer, and Mechanical.
The game rules use standard d20 skills with a large range of original "Feats", which in Big Bang include super powers and other abilities.""
