OG:Battlegrounds Lite.

PUBG LITE game reverse engineering, for educational purposes.

I want a free roam version of this game, which is why I'm working hard on the project.
And also to have control over the game, I want to do funny things.

In short, the game is working but needs several things fixed to make it stable and functional.

README! The game works, but it's not playable!

This repository is to demonstrate progress and how things are going and how they stand.

Don't expect too much for now.

Below is a list of problems that haven't been fixed yet.

I hope you understand.

Windows 11 Problems!

1.4.2.681: It doesn't work on Windows 11 22h2 and higher.
1.4.2.423: It works at 23h2 and below.
1.4.2.14: It works at 23h2 and below.
1.4.0.15: It works at 23h2 and below.

0.7.0.1: The h4tiux crack patch works on any operating system, from Windows 7 to the latest Windows 26h2.

🧍‍♂️ Character

• 🔴 Correctly updating character information in the inventory. such as keeping a helmet and other equipment even when they are unequipped.

🌎 World

• 🔴 Relevance correction based on distance from the camera's viewTarget. - This problem causes physics-based actors to fall when they are far from the host's camera.
• 🔴 DOORS, Yes, the doors are quite complicated; they neither open nor close, and they are not being replicated.
  • NOTE! Partially fixed, it works on the host, but the door is not replicated to the clients.

Other issues in newer versions were fixed by H4tiux, such as the camera in the battle royale plane, getting out of the plane, crash problems, and others.

Game Lobby

Lobby Code : -> ogbg_lobby

WORKS ON ALL VERSIONS OF THE GAME

READ

The lobby is just web code, so you can open it in your browser.

The game uses Coherent GT to apply web elements as UI.

It has several problems such as

• 🔴 Sometimes, repeatedly, or constantly, the asynchronous loading of game information via Coherent GT fails to respond and gets stuck in an infinite loading loop.
• 🔴 Clicks fail in the lobby; you have to move the cursor so that the command switching focuses on web elements.

The code is completely open source ❤️; if anyone has the knowledge, they can access the branch listed above and modify the code. It would help me a lot Since -> I don't have much experience with web coding 💔, I hate it and it's very annoying.

The following are parameter commands for the online lobby hosted on GitHub Pages.

If you want to use it offline, access the branch and follow the instructions.

@PUBGLite-Win64-Shipping.exe -UI -LobbyUrl="https://phikill.github.io/RE_PUBG_LITE/custom_lobby/index.html" -AllowJoinAnyMatchState -LOG -NOSPLASH

The -AllowJoinAnyMatchState parameter is required for creating matches; otherwise, you will not be able to.

1.4.2.681

1.4.0.15

0.7.0.1

NOTE: The server browser is fake for now, so ignore it. its a prototype

You can create simple matches in the custom_match menu. To play, simply open two instances of the game: one will be the server and the other the client.

PLAY/CUSTOM_MATCH/CREATE_CUSTOM_MATCH

Some parameters, such as TPP/FPP and the number of players in the match, don't work, so you can ignore them. and also the name of the match.

And the game mode works.

Default: It does not add any extra parameters to the map; it loads the map's default blueprint.
TRAINING MALE: This game mode loads the training mode with a male character; in this mode, the character does not take damage.
TRAINING FEMALE: This game mode loads the training mode with a female character; in this mode, the character takes damage but does not die.
BATTLE ROYALE FOREST: Battle royale game mode, but loaded by Erangel by default. works in the Miramar
BATTLE ROYALE DESERT: Battle Royale game mode, but loaded by Miramar by default. Works on Erangel.

PLAY/CUSTOM_MATCH/JOIN_FROM_IP_ADRESS

On this page, simply enter the IP address of the server you wish to connect to. More instructions below.

🕹️ 🎮 🌐 PLAY! | Creation of Match / Open Map | Join a Match

Remember, you need to open the program twice! this part is to turn the current process window into a host server, which is not playable.

To play, you need another instance and to join the match. as a CLIENT

These images below are an example.

The host cannot interact with elements in the environment, among other things; it is not meant to be played, only to host the game.

(1) Host (2) Client

0.7.0.1
Host
Client

1.4.0.15
Host
Client

You can create matches from the lobby in any version of the game except those mentioned later, and you can also use an SDK to open the map with DLL injection, or in the server panel.

STEPS TO PLAY

(1). First, create a match as host 👑🌐🗔.

• Make sure you have all the pre-configuration information, such as server port and the map's gamemode blueprint.

(2). You can join the match 🖥️🎮

• from the lobby by entering the IP address in the join from IP Adress option. If you are on the same computer as the host, simply enter 127.0.0.1 if everything is standard.
• If you're trying to connect using a different port or IP address, just try something like this.

on the page : CUSTOM MATCH/JOIN FROM IP ADRESS
(1) in case it's a different port : Example 9999
- 127.0.0.1:9999

(2) In case it's a different IP address but with the standard port : 7777.
- 192.168.15.15

(3) in case the IP address and port are configured differently : Example 4050
- 192.168.15.15:4050

(4) default local address, and default port

• 127.0.0.1:7777 The address of the same computer that is being hosted and the default port defined by Unreal Engine.

By default, the game opens on port 7777.

(1).You can change the port by adding a new parameter ?port= to the UWorld URL in Unreal Engine

• Like : open MapName?listen?port=7778

(2).Or you can use it in the program parameters -port=

• Like : PUBGLite-Win64-Shipping.exe -UI -LobbyUrl="" -AllowJoinAnyMatchState -NOSPLASH -port=9999

matchmaking works up to version 1.4.0.15, in higher versions like 1.4.2.423 and 1.4.2.681 the game crashes

Note: the fixes are in the releases; you just need to inject the DLL on the host side when the game is loaded and in the lobby. You can inject it during the match, but I recommend injecting it before any player joins the match or lobby.

Game Launcher

WORKS ON ALL VERSIONS OF THE GAME

I'm decompiling the launcher and making it in pure C, with support for Linux and even Windows XP.

Currently, I only have Windows, and I've disabled XP support for now, as it doesn't make sense.

You can download this branch here; it contains the source code and the binary file in bin/nt_64/.

Branch Link :Launcher Source Code

README!

(1). Currently, the launcher only serves to add a nickname, in this case, simply change the UID, and disable the Please run from launcher error message.

(2). If you are trying to open PUBG Lite 0.7.0.1 and are receiving a LauncherIpc.dll message like the one below.

• You need the crack that's in this release : 0.7.0.1 Crack Patch

That's all there is to it; you can't start the game from the Launcher, -> you have to start it Externally.

If you want, you can implement it yourself; the code is in C, using Chromium for web with the LIBCEF library for its implementation.

And be happy, the code is in the branch mentioned above.

Login Page - nickname only

Login Page - nickname Set CHICKEN in capital

Main Page - there is little here

The LauncherIpc.dll implementations work.

Nickname inside Game - set in launcher - lobby view 0.7.0.1

Nickname inside Game - set in launcher - Training Mode 0.7.0.1

IGNORE, OLD PHOTOS , the first steps of the project , It only works now on Windows 7 x64 or higher .

Cef Working o Windows XP

and the same code working on linux

Server Panel

I created this Server Panel to remotely control the server from a browser, view its status, and more.

Don't expect too much; when trying to spawn vehicles, there's a 99% chance your server will crash. But it works fine.

More implementations and bug fixes will follow in the future.

You can switch maps and gamemode blueprints.

The players' positions will be represented on the 2D map.

You can call Unreal console commands from the page; there are some tick issues at the moment, but I'll fix that later.

You can spawn vehicles from the page; there are some tick issues at the moment, but I'll fix that later.

You can kick any players you want out of the match.

Footnotes

1. NOTE! For now, the character is quite buggy when exiting the vehicle. The bugs are: character rotation and invalid activation of the underwater state. ↩

2. • NOTE! I made a quick fix, so this conflicts with the ALT FreeCam, but it helps with the punching gameplay.
   ↩

3. It works well, but needs improvement because it's quite broken. ↩
