M2TW Engine Overhaul Project is designed to expand the capabilities of the game Medieval 2: Total War.
EOP uses C++ and Assembly to modify the game's code in-memory and exposes this to the end user via a Lua API and the EOP Lua Plugin

Features

  • Hugely expanded Lua scripting system that integrates seamlessly with existing campaign_script scripts, hot-reload, new custom console, debugger and much more
  • Breaks the EDU limit allowing for more than 500 units in a mod
  • Place .fbx models anywhere on the strategy or battle map with full animation and texture support
  • Render .cas models for characters, settlements, forts, or anywhere on the map based on any kind of condition you can imagine
  • Play custom sounds or music with support for WAV, OGG/Vorbis and FLAC
  • Unlocks all vanilla console commands
  • Rome: Total War style tactical map viewer
  • Create your own GUIs and overlays using the popular ImGUI
  • New custom EDU system that allows the creation and modification of new and existing units without the need to restart the game
  • Play out Hotseat battles online and transfer the results back to the campaign map
  • Set your own limits for the number of religions, ancillaries, bodyguard units, building chains, max unit size
  • Set the boundaries of the number of soldiers in units
  • Fixed many engine bugs, crashes and oversights (e.g crashes when using berserkers in battle)
  • Edit the .worldpkgdesc for any settlement on the fly without the need to restart the game
  • Custom keybinding support
  • Added ability to write your own add-ons in C++. The library exports many different functions.
  • Utilize the packaged M2TWEOP GUI launcher with full customization support as well as the included EOP Health Checker or just allow your mod to be launched directly
  • Many, many more!
