Bug Fixes
Ice Gun kills can no longer be stolen by other damage while an enemy is frozen, so they now count toward Ice Gun quests and achievements.
Fixed the Mortar's Concussion in Tower Defence mode. A shell from a lower ranked Mortar no longer replaces a stronger Concussion already on an enemy. The strongest one now stays and the timer is refreshed.
New Wave Survival Difficulty
Insanity: A new difficulty level above Nightmare has been created for the Wave Survival mode. Insanity will be unlocked once an Extraction has been completed on the Nightmare difficulty setting after this update. The mode will provide +5 Salvage per boss wave. Players are not expected to complete this difficulty any time soon.
New Prestige mechanic
A new Prestige mechanic has been created so that you will have the possibility to upgrade your character even more. Once all character upgrades from the Quartermaster have been maxed, you will be able to prestige. A Prestige will wipe every character upgrade and refund 75% of the Salvage you spent on them. Each Prestige level will raise the maximum rank of every upgrade by one. A character can prestige up to 10 times in total.
Chaos Mode
Additional chaos rounds created.
The "All zombies are Walkers / Runners / Sprinters" modifiers will no longer spawn special infected.
Tower Defence
A new flying enemy "Rot Vulture" has been created and added into the Tower Defence mode. It moves slightly slower than the Rotwing but has a higher HP pool. The vulture can only be hit by the Sky Lance turret and the Tesla Coil. The Sky Lance will do full damage but the Tesla Coil will deal reduced damage.
The Summoner now raises 3 zombies per chant instead of 2.
Additional balance changes.
General Changes and Improvements
Visual improvements and additional performance optimisations.
The Gravedigger enemy has been renamed to "Summoner".
The Summoner now makes the same death sound as the other infected.
Any enemies that are spawned into the round (Boss throw, Summoner zombie etc) will need defeating before the round ends. For example, if you defeat the boss but there are still zombies on the map, the round will not end until they have also been defeated.
The Skateboard item has had the wheel positions fixed and has received a visual overhaul.
The icon art for most of the items has been improved.
Added a zoom in mechanic. Players will now be able to scroll the mouse wheel to zoom in their camera view. I would not recommend playing zoomed in but it's a nice to have.
