Three update patches for the game were released by developers Fields of Vision:
** BREATHLESS V1.1 and BREATHLESS V1.11 offer a number of bugfixes and gameplay enhancements. Most notably, they improve the speed and fluency of the 3D graphics engine (especially up/down movements for looking/shooting), add inertia to the player's movements, and generally make the game more configurable.
** BREATHLESS 3D ENGINE V1.1 68060 improves the sluggish speed of the graphics engine on 060 machines (dir: game/patch/Breathless060.lha). The sluggishness of the original is due to the 68060 being unable to directly execute 64bit divisions and multiplications, which are instructions that the 3D engine uses a lot.
