Art Shift: The game's art assets began as crude figures with basic animations for gameplay testing, but are slowly being replaced with beautiful "new art" characters and locations.(The popular fan explanation is that the spy is wearing fancy contacts that lets them see outside the visible spectrum.)

This is to make sure the spy has the best chance of blending in, and knows where the sniper is at all times. Acceptable Breaks from Reality: The sniper's laser can be seen by the spy when it's close, yet nobody else at the party notices this.
