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!
