The development teams left much to be desired... but no more! Featuring new units, 12-fighter squadrons, realistic speeds of projectiles, updated and more-canon build tree, and changed hardpoints. Also, cut content such as planets and some units will be added.
A quick overview of the Rebellion starting Galactic Conquest. You can see several new units, (as well as those missing text) and even a short battle clip vs Empire.
You will notice that some units appear on the build lists for all tech levels (1-5). This is unintended for some units (R41, CC7700 come to mind) and is a very quick fix that isnt high on the priorities list.
The land aspect for the rebels hasnt changed much.
You will see:
In-game Venators, Republic Corvettes (6 types), Mon Cal frigates, The Viscount Star Defender (Same as the SSD battle posted here), Several new fighter squadrons; Dauntless and Republic Class Star Destroyers (?), and several carriers.
If the video is choppy, blame Powerdirector.
