Insane Warrior is a cancelled game by Core Design, that was planned to be developed for the original Playstation. Assembler Games Forum user Decapicitated found a few screenshots from this lost project in the online portfolio of a former Core Design developer who worked on it. As we can read from Decapicitated’s posts:
“Insane Warrior was developed by Core Design and was unfortunately cancelled. It wasn’t exactly a playable game, more or less a tech demo. Part of the team which developed the game went onto developing Ninja: Shadow Of Darkness which was released September 1998. The game itself looked very similar in terms of the camera style, it was identical to Ninja. I also believe some of the ideas of this game were implemented into Ninja therefore, it could be quite possible to just call it an early tech demo of Ninja.”
“Yeah, it’s definitely a PSX exclusive. It was nothing more than a tech demo which was developed after Tomb Raider, but before Ninja as the team working on this was pushed on to making Ninja in 1997 to be released for 1998. This game got canned or the engine was probably re-used for Ninja. The game is very similar as I said before and these are the only screenshots in existence, I got these off a website which belonged to one of the devs a VERY long time ago; the website is now defunct”
At the moment there are no other details about this cancelled game. If you know someone who worked at Core Design between the original Tomb Raider and Ninja, please let us know!
