In the LA and night time environments you'll now find barrels you can grab and drop to climb on to reach higher areas of the wall. Grab using left grip - teleport has been reassigned to right touch pad.
Some users reported the trigger dead zone being too narrow which resulted in a constantly spraying can. The dead zone is now much wider.
The lower two quality levels for the game had perfectly flat walls (no normal maps) - these levels have been removed. Any users that were unknowingly stuck on these levels will see massive graphical improvements.
