Ninja: Shadow of Darkness
Ninja: Shadow of Darkness is an action beat 'em up video game developed by Core Design and published by Eidos Interactive for the PlayStation. The story follows a warrior named Kurosawa, who is tasked of ridding Feudal Japan of an unspeakable evil. Gameplay. The player character, Kurosawa, can combat enemies with hand-to-hand moves, magic spells, or weapons such as swords and throwing star that appear as item pick-ups. There are also pick-ups used to recover health. Development. Though "Ninja" was developed immediately following the popular "Tomb Raider", Core Design did not want  to be restricted to the "Tomb Raider" engine's interiors-only nature, and instead built the game engine for "Ninja: Shadow of Darkness" from scratch. The game was announced for release in August 1997 on Sega Saturn, PlayStation, and PC, and a near-complete beta of the Saturn version was unveiled at this time. The PlayStation version was a port of the Saturn version. Mid-development, programmer Derek Leigh-Gilchrist commented that the port "has involved taking a lot of C code across from Saturn and modifying the 3D-specific bits to use the GTE [Geometry Transfer Engine]. This all  worked fine, but it still wasn't fast enough to run the game at 30 frames per second, so I then converted the C code into optimized R3000 assembler with inline GTE code, which halved the processing time. "Ninja" now easily runs in 30 fps and has enabled us to start adding more detail to the game environment." The Saturn version created floor surfaces with the Saturn's Mode 7-style scaling, a feature unique to the console which allows it to perform scaling effects without burdening the CPU with geometry calculations, whereas the PlayStation must construct floors out of  polygons, a task which lowers the frame rate. Using the resulting performance benefit, the team tagged objects in the Saturn version with depth-cues, allowing them to create transparency effects in the game's water bodies. The PlayStation version was delayed for over a year, and the Saturn and PC versions were cancelled entirely. Reception. The game received an average score of 66.00% at GameRankings, based on an aggregate of 8 reviews. Gameinformer gave the game a 2.5/10, saying "Horrible graphics, bad controls, a pitiful excuse for a fighting engine, and no story add up to one word: sucks! Put  Ninja top pasture and play Tenchu instead."
