No one would've thought that being an exterminator could be so thrilling and suspenseful, but in "Desolation," that's exactly what it is. You have been assigned the extermination of a studio building, but what you find when you get in there is anything but ordinary. This is a puzzle game, rolled in to a thriller, rolled in to a shooter. Use the arrowed map at the top to move the character around. Use the mouse to aim and shoot. There are various weapons and tools for use, so choose wisely. Pick up clues along the way and find out what has happened at stage 4 in the studio.
