Game Modes and AI Expanded

Game Modes and AI Expanded seeks to expand upon the current framework.

Contents:
A new game mode "Invasion" where players must defend a series of capture points against an AI force. The map "Invasion Eden Central" allows players to play this new game mode.

A new game mode "Point Defence" where players must defend a single capture point against an AI force. The map "Point Defence Eden Monti" allows players to play this new game mode.

AI "players" added to conflict in the "CTI AI Eden" and "CTI AI Arland" maps.  The AI "players" will spawn, move towards, and contest enemy capture points.

This mod is currently a work in progress. There will be bugs. There are also features missing.
