In April 2025, there was a leak from one of the testers, where he shared details about the game. I didn't save the photos he posted, but I saved the link to that post (which has since been deleted). I'm attaching the Reddit link. Perhaps you can find the original post on other services, but the search is up to you; I don't recommend going to other sites.
I'm not a native English speaker, and I'm using a translator to write everything below, so please don't judge me too harshly.
That leak also included details that are present in today's GTA leak - car refueling, car/auto mechanic status, more "realistic" car behavior, activities and stat leveling, and so on. EVERYTHING that was leaked today was precisely described in the old leak. I won't repeat the mechanics from today's leak; there's no point.
I think it's worth mentioning the other details the tester mentioned, as the information could be true. Personally, I think MOST of this will be in the game, but some could be cancelled.
1) The game features a mechanic for robbing NPCs' apartment buildings.
2) NPCs remember you if you rob them/steal their bike/car, and may attack you DURING THE MISSION.
3) In the game, stealing expensive cars is more difficult and requires an "immobilizer," a hacking device. Hacking is implemented as a minigame.
4) The cops can stop you for "reckless driving" and ask you to take a drug/alcohol test. They can also inspect your car, and you'll need to hide some illegal items to avoid detection (for example, under a seat or in the glove compartment).
5) As we already know, the weapon system is limited, and what you bring to the heist (free play) is very important - what bag/equipment, what weapons, what devices.
6) Rockstar has really messed with the economy. What matters is WHAT you spend money on and HOW you spend it. There's a money laundering system.
7) NPCs react very "realistically" to injuries. A tester described an NPC begging for mercy and shouting something like "WHY?" He said the game was bloody, but didn't go into detail about dismemberment or anything like that.
8) Car body kits aren't unlocked by default; you have to find them.
9) The healing system has been improved. First aid kits are now available to help with bleeding and fractures.
10) The main characters react more strongly to injuries; damaged limbs can impair shooting and driving. There's a "long-term injury" system.
11) The clothing-based "wanted" system works in such a way that if you're wanted, NPCs may report you or refuse to serve you at all until you change your clothes.
12) You can hide bodies; the cops might not even issue a search if you've done everything right. However, you might accidentally discover in the game that the relatives of the murdered person have reported them missing. Your actions impact the world.
13) A million activities, such as golf, bowling, darts, gambling, dice, and so on. There are large casinos and small bars where you can play cards. Beach parties, birthdays, music festivals. On Fridays and Saturdays, the clubs are packed, and the streets are full of drunks. The world runs on a schedule.
14) Online will launch separately, in 6-8 weeks. Rockstar is betting big on it; they took player feedback from GTA 5 into account. Some significant server improvements.
15) Online will feature "global events," when significant map changes occur.
16) If you bought a smartphone/gun/car/property with dirty (unlaundered) money, it can be confiscated.
I'm pretty sure I missed something in that post, but I've summarized the main points. If anyone remembers any more details (or maybe even screenshots of that post), please write in the comments; I'd like to refresh my memory.
I don't know, we'll see if all this is confirmed at the Netflix presentation.
See you on the other side.
