APB has always been the game where everyone thinks everyone is cheating, but the majority aren't.
Since LO first changed the anti-cheat, every single public APB hack was taken down.
No one can purchase a cheap public hack anymore, as of like 2018. This means the only cheaters left are paying absurd prices for private hacks (which will likely come with a free RAT), or they're coding their own (which requires bypassing BattlEye and some braincells). Sure, if you have a good undetectable private cheat then you're pretty much invincible, but that's the case in any game and is usually the minority. These people probably exist in APB, but I can't imagine there's many. Its not even worth the time for anyone with the development knowledge to code cheats for this game, considering how little money there is to make off of it due to the lack of players.
The APB playerbase's average skill level is a tiny fraction of what it used to be in 2014-2015. Absolute night and day difference to now.
I've seen such a tiny amount of people cheating in the past 4 years. If there's one single thing LO actually did, it was eliminating the majority of script kiddies.
Bottom line is: get gud.
Or go play a better game instead.
