The authors consider strings with an N = 2 local superconformal symmetry on the worldsheet. The critical dimension for this theory is four (two complex dimensions) with the signature. A Kahler function giving rise to self-dual gravity is the only physical degree of freedom of this theory. Some miraculous symmetries are observed corresponding to the exchange of worldsheet and target moduli. The open and heterotic versions of this string theory correspond to self-dual Yang-Mills fields coupled to self-dual gravity in four dimensions.
