+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the

+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable

+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed

+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,

+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a

+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing

+# GTA Tools

-![](https://i.ibb.co/SwdWRfGj/gta-tools-WEQ02u-ROT5.png)
+A toolset of convenient things for GTA V Online.
+
+![](https://i.vgy.me/HVBklM.png)
+![](https://i.vgy.me/yzRGjG.png)
+
+> [!NOTE]
+> I have been forced to move this project from [GitHub](https://github.com/elituf/gta-tools) to [here](https://gitlab.com/futile/gta-tools). Sorry for the inconvenience. From now on you may always find the project source code via the redirect at [futile.eu/gta-tools](https://futile.eu/gta-tools).
+
+## Installing
+
+**Option 1** — <ins>Download</ins>  
+Download the latest release [here](https://gitlab.com/futile/gta-tools/-/releases/permalink/latest/downloads/gta-tools.exe) and place it somewhere convenient for you, such as Documents. You could then make a shortcut titled "GTA Tools", and pin it to taskbar or Start.
+
+**Option 2** — <ins>Build from source</ins>  
+You will need Rust, which you can get [here](https://rustup.rs). Then, clone this repo and navigate to it. At this point, you should probably `git checkout x.x.x`, where `x.x.x` is the latest tag. You can then run `cargo build --release`. Once you do that, you can use the binary located at `.\target\release\gta-tools.exe` in the same way as **Option 1**.
+
+> [!NOTE]
+> It is recommended to always use an up-to-date version of GTA Tools from [releases](https://gitlab.com/futile/gta-tools/-/releases). You can also easily access this repository by going to the <kbd>About</kbd> page of GTA Tools and clicking the <kbd>git</kbd> button beside the version number.
+
+## Guide
+
+Every feature of GTA Tools works for both the Legacy and Enhanced versions of the game. GTA Tools requires administrator access.
+
+#### Game
+
+This section is quite simple.
+
+<kbd>Launch</kbd> — Starts your game on the chosen launcher and game version.
+
+<kbd>Force close game</kbd> — Kills all game processes. The button requires a second press after the first one for confirmation. This *does not* touch Rockstar Games Launcher or any other processes, only ones named `GTA5_Enhanced.exe` or `GTA5.exe`.
+
+#### Session
+
+This section also has two features.
+
+<kbd>Empty current session</kbd> — Clears your session of players[^1] by blocking the game's network access for 10 seconds, then unblocking it. This can be useful in numerous ways:
+* You are stuck loading into a session
+* You are stuck loading into an interior
+* You are about to get griefed while doing a freemode mission
+* You want to quickly get a "new" session
+
+<kbd>Anti AFK</kbd> — Prevents you from getting kicked for idling by pressing keys on your keyboard every 60 seconds. At present, those keys are `VK_NUMPAD4` & `VK_NUMPAD6`, due to being a relatively good balance of keys that the game actually registers but don't interrupt gameplay too much if they activate while you're playing. You *must* be tabbed into GTA V for <kbd>Anti AFK</kbd> to work. While toggled, <kbd>Anti AFK</kbd> will only activate when all of the following conditions are true:
+* The `Grand Theft Auto V` window is currently focused
+* None of the designated keys are currently being pressed[^2]
+* The mouse cursor is not currently visible[^3]
+
+#### Network
+
+<kbd>Game's network access</kbd> — Blocks/unblocks GTA V's entire internet access using the Windows Firewall. This feature can also be changed to <kbd>Rockstar save server access</kbd> via the **Network** dropdown of the settings. When in this mode, instead of blocking the entire game's network, it will only block the Rockstar save server at the IP `192.81.241.171`. The IP can also be changed in the same settings, if ever needed.
+
+This feature is primarily useful for **replay glitching**, which is an exploit that allows you to complete any heist/mission finale, get the money for it, and then be able to do it again right away.
+
+<details>
+    <summary>How to do a replay glitch</summary>
+
+1. Get to the finale of a heist/contract/mission series, such as **The Contract: Dr. Dre**
+2. Complete the finale as normal
+3. Right *after* the **HEIST/MISSION PASSED** screen you get when you complete a finale (basically, when your cut is being shown), <kbd>Block</kbd> the game's internet access
+4. After a few seconds, you will be shown an error screen and kicked to the main menu
+5. At this point, <kbd>Unblock</kbd> the game's internet access and load back into online
+6. Finally, spend any amount of money, and you should receive the finale cut, but also be able to go play the finale again immediately
+</details>
+
+<details>
+    <summary>How to do a replay glitch (save server method)</summary>
+
+1. Get to the finale of a heist/contract/mission series, such as **The Contract: Dr. Dre**
+2. At any point before you complete the finale, <kbd>Block</kbd> the save server access (for example, at the beginning of the mission)
+3. Complete the finale as normal
+4. After loading into online, exit to story mode
+5. At this point, <kbd>Unblock</kbd> the save server access and load back into online
+6. Finally, force a save by changing your outfit, and you should receive the finale cut, but also be able to go play the finale again immediately
+</details>
+
+
+
+[^1]: Technically, it just makes you lose connection to the session. But it looks like everyone left you instead.
+[^2]: Otherwise, if you are, for example, using those keys to fly a plane, <kbd>Anti AFK</kbd> activating could cancel the input.
+[^3]: Specifically, the Windows mouse cursor, not the in-game mouse cursor. This check is mostly used to prevent typing while you are in the Rockstar overlay.
