Silent Steel is a 1995 submarine simulator computer game by Tsunami Games. It was created during the influx of interactive movies during the 1990s. The game is composed almost entirely of live-action full motion video, with sparse computer-generated graphics depicting external shots of the boat during torpedo attacks and atmospheric fly-bys. A version playable on DVD players was released in 1999, following from a DVD-ROM version in 1997. The DVD-ROM version was the first video game formatted for DVD. A sequel, Silent Steel 2, was announced by Tsunami for release in 1997, but it was cancelled.
