Screwed by the Network: Although GamersFirst did rescue the game initially, some of their decisions with the game have alienated a lot of its' playerbase. Problems with game balancing, insufficient content releases and a significant price hike in the premium content have led many of the long-standing players to consider the game 'dead'. The rumor of corrupt devs unbanning hackers, even if false, did not help matters.
The second trailer showcased Zombie dual wielding machine pistols and La Rocha picking up a minigun. Neither of which made it in the game.
One of the early presentations showed melee weapons, these aswell did not made it into the game.
Old concept art shows that it was original planned for weapons to be faction seperated to increase diversity between the sides, both visualy and in terms of gameplay. Likewise for better versions of guns to be visualy different from the lower version.
Multiple districts with different themes had been planned, there were also two social districts planned one for each faction. The social districts themself were planned to have a movie theater where players could upload recordings from missions.
Miko Wong, who is mentiod in the fluff E-mails and some item description actualy had an ingame model. It's unknown what her purpose was planned to be.
There are youtube videos showing unused animations that never made it into the game.
From Reloaded Production comes the APB: Vendetta Kickstarter. The concept was for a fast paced arena shooter in style of Quake 3, using Le Parkour movement and being able to play the contacts of APB Reloaded, who would each come with different abilities. The developers further promised updates each week and for additional stretch goals, including being able to import your APB:Reloaded character and being planned to come to Playstation 4. However despite positive reports by gaming sites, the overall reaction of the APB playerbase and various comments was cold at best. The Kickstarter barely got support and no updates were made after the first week. In the end it only reached 25,000 dollars of the 300,000 they needed.
