 In 2004, Tecmo began releasing low-priced episodic installments of "Ninja Gaiden" for AT&T and Verizon mobile phones on both BREW and Java platforms.The official English Tecmo Games' mobile website advertised it for a future release along with a mobile version of "Tecmo Bowl".The company planned to release the entire game throughout 2004 in a series of four installments—similar to what Upstart Games did when they ported the NES version of "Castlevania" to mobile phones.
