"688 Attack Sub" is a simulation for MS-DOS, based on the Los Angeles class of Fast Attack submarines in the US Navy. Perhaps THE most advanced and innovating submarine simulation of its time, 688 does it all. From the well modeled command stations, immersive graphics and sound to the challenging missions on offer, 688 delivers a very unique experience for 1989. While fine games such as "Silent Service" and "Red Storm Rising" had already pioneered concepts such as a control room from which you move between stations (Silent Service) to the identification of warships based on sonar signatures (RSR), 688 Attack Sub too the concepts to the next level and added more intricate layers to them. Such as feedback and reports from the crew which is represented visually through pop up images, a side-scanning sonar producing a 3D real-time image of the sea bottom and ocean environment around you, the representation of biologics in the ocean, and even being able to play as the enemy / Soviet side!

In many ways I have found 688 to be a candidate for the best DOS subsim, due to all its great features and its look. My only gripe with the game was always the look of the control room of the sub, also known as the conn. It felt in some ways that it was drawn as an afterthought, as it does not really match the overall style of the otherwise clean and professional command stations you move between. Anyway, this is of course a matter of taste and opinion. It was my hope to someday make a new one, and finally here it is. I have tried to keep the style clean but detailed, and true to the real LA class interior. There are of course some omissions and compromises due to the fact that this is a 320x200 image, and to keep the graphics within the mouse navigation confines that are hardcoded in the game. Also, so far I have only changed the american sub graphics, the Soviet Alpha class conn is still the same.

This took some sweet time to draw from scratch. I also decided to update the splash screen to match, for this I sourced an image from the US Navy archives. I hope this mod will bring new immersion and enjoyment to 688 Attack Sub!
