Platform Specific Changes

PC

• Implemented Alpha Widescreen support for PC platforms. Players will now be able to play MOUSE: P.I. For Hire in widescreen.
  • Note: This is an Alpha Feature as weapons and first-person animations are still hand-drawn for a 16:9 frame, so there may be a hard edge visible for some weapons and animation sprites. To support ultrawide in full without these drawbacks, every weapon and animation will need to be redrawn to properly scale to the ultrawide perspective, and this will take some time.
