Danger from the Deep, often abbreviated as DftD, is an open-source World War II German U-boat simulation for PC, striving for technical and historical accuracy.[1]
The project was registered in 2003 on sourceforge.net and is since then developed as open source software under the GPLv2. In 2004 it reached beta status.
The game targets Multi-platform, supporting FreeBSD, OpenBSD,[2] Mac OS X,[3] Linux distributions, and Microsoft Windows by utilizing SDL and OpenGL. Hardware addressed is OpenGL 1.5 (while recommending "OpenGL 2.0 or greater"[4]) with around 256 MB of RAM, 1 GHz processor and common PC input devices (keyboard, mouse).
Development is intermittent. As of June 11 2020 the latest commit to the Git repo was May 10, 2020.[5] The last downloadable release was May 8, 2010[6]
A Linux Journal review from 2010 received DftD quite positive.[1]
In 2004 The Wargamer recommended the game to "serious sim gamers" which should "head over to Danger from the Deep's official web site and take a look.".[7] In 2011 an Ars Technica article on the history of simulation games noted Danger from the Deep as: "These days, submarine sims [...] are kept alive by the open-source Danger from the Deep".[8]
The game was downloaded between 2003 and April 2017 1.3 million times alone from SourceForge,[9] chip.de counted another 100,000 downloads.[10]
