The game is several updates behind compared to the Steam version and is missing newly added features.
There's an issue with this version of the game where if you move your mouse slowly the game camera won't move. On top of that the X and Y axis scaling is way off. These issues makes aiming a nightmare and it affects your camera whether you turn on Y-axis aiming or not. This issue is not present in the original game and is not present in any other Build Engine game such as the Duke Nukem 3D 20th Anniversary Edition, Blood Fresh Supply, or Ion Fury. There is a source port version of Shadow Warrior through eduke that is free, comes with the free 2 expansions, and doesn't have the mouse issue. This isn't acceptable from a company to release and then never patch when it's clearly an issue created by the developers of the Classic Redux edition.
