Destroy all enemy buildings.
Artanis, Mengsk, and Gerard DuGalle have united together to defeat Kerrigan once and for all. Pick one to control and eliminate Kerrigan. Beware, as her forces are strong and she will use the Zerg to eliminate you and your allies.
Use Terran forces to push into the enemy base.
Or use the Protoss forces to push into the enemy base, but beware as their defenses are strong.
However, with enough power and force, surround the enemy and slowly whittle away the defense before you finally conquer and destroy Kerrigan's Swarm once and for all.
Thanks for playing and trying out the Reverse Campaign. This series was meant to be simple reversal of just switching the enemy AI and the player spot. As a result, not every mission may necessarily be fun just due to the premise of the situation. I learned a decent amount from the series (such as making it to true to the original doesn't make it good since mineral and building placement isn't great). Furthermore, learning better ways to make "custom" AI looking attacks without using any EUD triggers. Due to the simplicity of the situation, I had assumed that most of the missions would take only a few hours to make (the Original Starcraft Reverse Campaign sees this a lot). However, I was able to experiment with splicing and nitpicking certain audios (even if its a bit repetitive) to make "somewhat" believable mission briefings as well as modifying starting units to still make playable and somewhat enjoyable missions (at least to me). I spent the most time on this Zerg version as it has the most modifications and and triggers (excluding the last mission). Still, I think the new objectives provides more fun versus the "higher difficulty." Of course that also means that many users may be turned off from the later missions that may have been enjoyable to others (due to the simple nature of the first set of missions as well as their higher difficulty).
