This is the Battle of Kashyyyk mission from Star Wars Episode 3 for Star Wars Galactic Battlegrounds Clone Campaigns.
An infamous RTS game created by LucasArts, it was largly based off of Age of Empires, and was considered the better Star Wars RTS of the time (Others bieng Rebellion and Force Commander). Despite its age and aged appearence, it still has a small but loyal following at Heaven Games, which hosts a vault of tools which make modding the game a rather simple task.
Craftan99 here to bring you the good news.
Chapter II is about to be rendered as soon as we get the Commander Gree voices from my Sound Artist.
Thanks to him you get to hear some awesome sounds, made by him too.
Thanks to every other voice actor who helped us give a wide collection of voices to work with.
The video is about 10-11 minutes long featuring the events after the destruction of the CIS Battlecore.
