IDA Pro CS2 Reversing Tools

A collection of IDA Pro plugins designed to automate and streamline the reverse engineering of Counter-Strike 2 and Source 2 engine binaries.

Since the CS2 (or other Source2 games) are updated on regular basis, it's not making life easier for a reverse-engineer that is actively reversing the game. In order to make the reversing of new CS2 binaries easier, this plugin introduces several tools that may help along the way.

The plugin includes tools such as automatic interface renaming, which automatically detects global interface variables used in the codebase and renames them accordingly. For instance, g_pVApplication001 or g_pVEngineCvar007. Another tool is the convar renamer, which does a similar thing where it automatically detects convars/concommands across the IDB and renames them.

Happy Reversing!

Note

This repository uses the ida_domain IDA Pro SDK.

Features

• Interface Table Renamer: Automatically locates and renames Source 2 interface pointers (e.g., ICvar, IEngineClient) based on their interface identifiers
• ConVar/ConCommand Renamer: Renames global ConVar and ConCommand variables based on their registration string names
• Dump Marked Pseudocode: Exports pseudocode for functions marked via Hex-Rays Mark/unmark as decompiled into a single output file
• Execute All Tools: Runs every available tool in sequence from a single menu action

Requirements

• IDA Pro 9.0 or later (with ida_domain API support)
• Python 3.x
• PyQt5
