Not sure what all was left out but here are some old ones.
Fixed player vehicles not able to damage Hellbug Blast Pod.
Moved the spawns outside the building in Freight Yard so people can’t be trapped inside any more.
Fixed an exploit in Scrapworks Salvage that allowed players to skip past a majority of the Co-op Map and start the Boss Encounter.
Added Elemental Hellbug variants to Island of Lost Soldiers.
Smoothed out the spawning of the additional enemies that accompany Jackleg Joe for a cleaner, more manageable experience.
Added new Volge LMGs. (Not old but are we getting more than ONE)
Adjusted time and cost for weapon remastery.
Shotguns are being tuned to bring them in line with the other weapons and personalities we want to obtain with each type of shotgun.
Mag Size Changes: We have made changes to the mag size of all bonus size mods and rarity bonuses. This was largely due to shotguns getting more shots per clip then intended.
Rarity Bonuses that increased Mag Size have been decreased.?
Clip Mods that increased Mag Size have been decreased.
These two types of Shotguns are being tuned to bring them in line with the other shotguns.
* Rate of Fire change for the VOT Auto Fragger: We have made this change due to speed at which a player could kill its intended target. This weapon now has slightly lower rate of fire to bring it in line with the other combat shotguns.
* Recoil Increase in the TACC Auto-Shotgun: This change was to add a bit more variance in the recoil with the amount of shells it could shoot from its high mag capacity.
Cluster grenades now properly update kill counts within pursuits.
Mods can now be broken down to Ark Salvage.
Vendors are available during the Dodge Challenger Race events to sell special Challengers. Find them scattered around the world and by the start of the races.
Added ability to choose which regional server (North America/Europe) you connect to. (Note: Your characters remain associated with your original server; they do not switch servers.) (Not really old but already implemented)
These are the ones I noticed.
