Swaps all of the units and visual effects around so that all three factions can be played. The balance changes included in the mod address numerous long standing complaints about the original game while the faction swap provides a fresh experience to the gameplay. The mod has been built from scratch with full compatibility on all maps and missions in mind: Any map that worked with the original game will work with this mod. The campaign can also be played either as it was in the original (with the new balance changes included), or by using the previously inaccessible Terran units instead.
In version 3 the Viron campaign in Reversal mode is now played with Terran units almost exclusively. Much like the graphical fixes & updates, its something I wanted to do from the very start but didn't quite get to work right.
So you have removed the Big bad terran tank, anny chanse that it is at least unlockable in the last missions or something?
I wasn't going to make it available in the campaign anymore because it was an all or nothing deal: Either the tank was always available in all missions or it wasn't. I felt this made the early missions too easy so when I started work on version 3 I removed it.
I've since come up with a few ideas on how to keep the super tanks in the last few missions only, so I'm probably going to do exactly what you asked!
