Technical Notes
------------------------------------------------------

If you are using a setup with more than one monitor you may experience
problems.

The game uses SDL2 (or SDL3 with -DUSE_SDL3=ON). Multimonitor setups
may have quirks depending on your driver; SDL3 generally handles
Wayland better.

Your graphic-card must support OpenGL 2.x or superior for decent
graphics. HARDWARE ACCELERATION is required.
Your graphic-card MUST support HARDWARE ACCELERATION.

The game won't run on machines with a Cirrus Logic 4MB card.

We like pie.

Gameplay
------------------------------------------------------
The game recommends a resolution of 1024x768 strongly.
It can be played with different resoultions, but will
look ugly. Just type dangerdeep --help and check for
resolution switching. Using a higher resolution is not as
bad as using a smaller, though.
General rule: what does not work that is just not
implemented yet ;-)

Closing words
--------------------------------------------------------
This game is made as tactical simulation that tries to be
as realistic (historical and physical) as possible.
It is NOT meant to glorify war in any form.
Many thousands of people died in the Atlantic during 1939-1945
on both sides.
