This update comes with the new Payload Mode (available some time after the new update goes live) and the updated Survive Till Dawn - Halloween mode. The Darkest Night will be taken offline for further tuning. 

Other enhancements: characters can now leap in mid-air to reach previously inaccessible places; new vehicles such as the amphibious BRDM-2 and helicopters have been added to make traveling more mobile; exploding fuel drums are now in the game for laying traps.

As for weapons, the M16A4, Vector, UMP45 and MK47Mutant have all been tuned. The famous Desert Eagle has also been added.

The performance has also been improved: now it runs smoother but consumes less power and therefore less likely to cause your device to heat up; weapon and outfit display have been enhanced; the touch controls have been tuned to reduce errors in movement after opening scope; room and inventory systems have also been improved.
And one more thing - graffiti is now available!
