Double Trouble is the second mod made by Ryan de Haast. It features 35 levels in a heavily coded EXE based on registered Wolfenstein.
It was more than three years in the making before being released, and was intended as a sequel to Rising Evil. Many new features include animated walls, many new doors, animated objects, outside atmosphere, textured floors and ceilings and loads of others.
Mapping is generally good but certain areas suffer from emptiness and repetitiveness. The experience is still not spoiled due to the atmospheric coding.
It remains available in DOS only.
