### Summary of GTA 4 Beta Build Leak Analysis
A **beta build of Grand Theft Auto IV (GTA 4)**, dated **November 22, 2007**, was leaked from a development kit. This build sits chronologically between **Trailer 2 and Trailer 3** of the game's pre-release materials, representing a transitional phase where Trailer 2's content was very different from the final game and Trailer 3 was mostly close to the finished product.
This beta build is **not fully playable**; it consists mainly of recovered game files without complete functionality or the ability to run on an Xbox 360. The analysis focuses on assets and data extracted from these files, revealing intriguing differences and cut content compared to the final release.

### Key Findings and Insights
#### Weapons
- **Silenced Pistol**: Official model recovered, confirming fan recreations were accurate. However, the silencing feature was *not implemented*.
- **Nightstick**: A melee weapon originally intended for police, fully present with stats.
- **Golf Club**: Present as a weapon, surprising as it was thought to be exclusive to the "Battle of Gay Tony" expansion.
- **MP5 and Zastava M70**: The beta MP5 retains final-game model but with temporary beta textures; the beta AK-47 (Zastava M70) is absent, replaced by the final version.
#### Characters
- **Beta Michelle** (from Trailer 2): Model looks closer to final than previously thought, with notable differences in facial appearance and hair styling.
- **Baz Run and Jeremy St. Ives**: Hosts of the in-game TV show "The Men's Room," with both in-game and cutscene models present. Baz Run's textures are higher quality than in final game's "Ballad of Gay Tony" files. Unused accessories like boxing gloves for Baz are missing here.
- **Busker Model (young version)** and **Pachy's Beta T-shirt**: Newly discovered models/textures, with Pachy's shirt texture partially used as detail maps in the final game.
- **Bulgarian Henchman**: Contains unusual textures unrelated to the character's ethnicity or role, an unexplained oddity.
Other checked characters such as **Ivy Johnny, Luis, Jimmy Fitzgerald, and Jimmy Pegorino** show no beta differences from the final game versions.

#### Models and Animations
- **Vehicles**: Unable to examine model differences due to file format restrictions; only textures are accessible.
- **Animations**: Some beta combat and movement animations differ slightly, with indications of beta walk stances closer to early trailers.
#### Audio and Cutscenes
- **Cutscene Extensions**: Some cutscenes in this beta build are longer than in the final game, including additional dialogue and interactions, though full rendering and playback are limited.
- **Radio Content**: Some beta audio tracks were found, potentially restorable, but the complexity of integrating them with final game audio is unclear.
---
#### Mobile Phone Models
- Multiple **beta phone models** were found, including:
- **CJ mobile_01 and CJ mobile_02**: Similar to final game phones but with asymmetrical and extended features.
- **CJ Mobile 3**: Matches the "Whiz" phone model used only in cutscenes in the final game.
- **CJ mobile hand_and**: Resembles the "Badger" phone seen in Trailer 2 cutscenes.
- **Unseen Flip Phone (CJ_mobile_LD_2)**: A never-before-seen flip phone model, possibly animated to open/close.
- **CJ_mobile_LD_3 and Others**: Similar but distinct from final game cutscene Blackberry phones, with notable button layout differences.
Some phone models appear incomplete or partially converted, suggesting possible missing parts or animation sequences.
