Moon Warrior

Moon Warrior is a cancelled game that was being developed by SCEE Cambridge Studio in 1999. It was due to be released on the PlayStation. The earliest known public mention of the game came from then SCEE president Chris Deering whilst he was answering press questions during E3 1999, where he referred to the game as a "top secret project." 23 years later, the game's designer, Tameem Antoniades, recalled the project in an interview with NME. A few months after the interview, on April 4, 2022, Build 0.05 of the game from April 28, 1999, was made publically available.

Several pieces of artwork from the game were on display during the Gaming Generations exhibition held by the Centre of Computing History in Cambridge throughout 2021 and 2022.

Gameplay
Antoniades, the game's designer, described it as "kind of like Metal Gear Solid, but Kung Fu." The protagonist of the game was going to be a Shaolin monk.

Development
Moon Warrior was pitched by Tameem Antoniades to Sony some time after it had acquired the studio. While Sony was interested, Antoniades allegedly encountered resistance from the old hands at the studio, who had had their own pitches rejected. As a result, Moon Warrior had no internal support. This eventually led to Antoniades leaving the studio and founding Just Add Monsters along with Nina Kristensen and Mike Ball.
