Update 1.05
Co-operative play now available for both DLC missions ("Hunt The Grey Wolf" and "In Shadows").
Added a setting for "Empty Lung Zoom" to allow toggling the additional zoom effect when entering empty lung (and extend the multiplayer settings/filters to support it as an option).

Bug Fixes:

Steam cloud now working.
Fix a potential hang on the Sniper Elite 3 logo screen due to corrupted stats in profiles.
Multiplayer: Fix an instance of player invulnerability in multiplayer matches.
Multiplayer: Join-in-progress now takes the player to the lobby to allow character and loadout selection rather than pulling them directly in to game.
