How to Extract and Modify Prototype 2 Cells RCF Files
Prototype 2 is a popular action-adventure video game that features a variety of models, textures, sounds and other assets stored in RCF files. These files are compressed and encrypted archives that can be extracted and modified using some tools and techniques. In this article, we will show you how to unpack and edit Prototype 2 cells RCF files, which contain the data for the game's infected enemies.
What You Need
To extract and modify Prototype 2 cells RCF files, you will need the following tools:
A copy of Prototype 2 installed on your PC.
A hex editor, such as HxD or Hex Workshop.
A RCF extractor, such as QuickBMS or RCFTool.
A DDS converter, such as DDS Converter or Paint.NET.
A 3D model viewer, such as Noesis or Blender.
How to Extract Prototype 2 Cells RCF Files
To extract Prototype 2 cells RCF files, follow these steps:
Locate the cells.rcf file in your Prototype 2 installation folder. It is usually located in C:\\Program Files (x86)\\Steam\\steamapps\\common\\Prototype 2\\cells.rcf.
Make a backup copy of the cells.rcf file in case something goes wrong.
Open the cells.rcf file with a hex editor and look for the following hex values: 52 43 46 00. These are the header bytes that identify the file as an RCF archive.
Change the header bytes to 5A 4C 49 42. These are the header bytes that identify the file as a zlib compressed file.
Save the modified cells.rcf file as cells.zlib.
Open the cells.zlib file with a RCF extractor and extract its contents to a folder of your choice. You should see a lot of files with names like cell_01_01_01_01_01_01_01_01_01_01_01_01_01_01_01_01_01_01_01_01_01_01.dae, cell_02.dds, cell_03.wav, etc.
How to Modify Prototype 2 Cells RCF Files
To modify Prototype 2 cells RCF files, follow these steps:
Pick a file that you want to edit. For example, let's say you want to change the texture of the first cell model. You will need to edit the cell_02.dds file, which is the diffuse map for the cell_01.dae model.
Open the cell_02.dds file with a DDS converter and convert it to a PNG or BMP format that you can edit with any image editor.
Edit the image as you wish. For example, you can change the color, add some details, or draw something funny on it.
Save the edited image as cell_02.dds again and overwrite the original file in your extraction folder.
Repeat steps 1-4 for any other files that you want to modify.
When you are done editing, you will need to repack the files into a new cells.rcf file. To do this, use a RCF extractor again and select the option to create a new archive from your extraction folder.
Name the new archive cells.rcf and save it in your Prototype 2 installation folder. Overwrite the original cells.rcf file if prompted.
Launch Prototype 2 and enjoy your modified cells! 061ffe29dd
