If you are looking for where to start modding POSTAL 2, you've come to the right place.


POSTAL 2 runs on the Unreal Engine 2 by Epic Games. As such, mods in POSTAL 2 come in two forms: Mutators and Total conversions


A "Mutator" mod changes or "mutates" the game on some fundamental level. This includes (but is not limited to):

  • Adding new/custom pawns
  • Adding new/custom weapons
  • Adding new/custom maps
  • Modifying existing pawns
  • Modifying existing weapons.
  • Modifying existing maps

Total Conversions[]

A "Total Conversion" can best be described as creating a new game on top of the existing game infrastructure. Examples of this include:

This may seem strange at first but keep in mind that POSTAL 2 itself was built on top of Unreal 2: The Awakening, with addition code merged from Unreal Tournament 2003 (see the FAQ).

Getting started[]

In order to start, a legal copy of POSTAL 2 is necessary. Preferably the Steam version which is the most current version (5025). This also gives access to the POSTAL2 map editor, POSTed, and the Unrealscript Source Code. In addition the following tools are needed:

  • A text editor used for coding in Unrealscript (Microsoft Visual Studio is recommended by Epic Games but may be too advanced for those new to coding)
  • Modeling software needed for making custom pawns/weapons (3dsmax is recommended)
  • Image editing software for making textures and 2d elements (Photoshop is recommended)


  • FAQ (Frequently asked questions for those new to modding)
  • POSTed (an overview of the Software Development Kit)
  • Unrealscript (an overview of the scripting language)

Modding resources[]

  • POSTAL 2 coding tutorials on Moddb (An archive of tutorial that were originally on the Running With Scissors website. Note that these are outdated but much of the knowledge presented is still useful in the current version.)
