It's still in it's early stages. I have plans for the future, and how it's going to end but I'm mostly focusing on how it's going right now.
It all started with me just making random maps for fun. It's after that that I got into the lore and tried to apply a story to it.
So, a group of terrans and protoss - survivors of the Brood War (this campaign takes place right after it's end) are cut off from their main forces in a remote part of the sector. They band together for now, to defend against their enemies - the Swarm taking the system from one side and another terran group from the other.
First they only have to deal with the Terran group, but soon the Zerg start moving in. Their force consists of 2 protoss tribes and 1 terran organization. When the zerg swarm starts moving in, they decide to abandon the system and get away, but one of the protoss tribes is against the idea and they want to fight the zerg directly. The planet being attacked by the zerg now is under control of the enemy terrans (the Kel-Morian combine) and the protoss tribe want to attack them there.
So in this map, on one side are the zerg, on the other the protoss, both hostile, and in the middle is the terran army. The player is playing as UED remnants. They were left on another planet so they avoided Kerrigan's purge. There was only a few of them so they were conscripted by the Combine. They are fighting alongside the combine, but there is enmity between them. After a big attack, the protoss tribe leader commends the UED commander - says the he is a good warrior and he senses that he doesn't trust his commander so he offers him a chance to desert and leave the planet - in exchange for not defending the combine outpost. They accept - now the player's enemy is also the terrans. You have to take the main hero as well as most of his army back to your main base safely through enemy fire to win the mission.
That is the story so far, I'm currently working on the next map.
In the next part, the UED remnats escape, while the protoss and zerg fight on that planet. They come across another group of UED remnants that are working together with the terrans and protoss who are trying to escape the system to flee from the zerg swarm. The only way out of the system is assaulting a space platfrom that the combine owns, full of weapons and ships.
The OTHER UED remnants (which is a group of wraiths) has found a weakness in the platform through which a small strike force can get in and infiltrate.
So the plan is like this:
-The terran remnat group from this system distracts the platform's defences with a direct assault of battlecruisers and wraiths
-the UED remnants get into the station through the secret passage, infiltrate it and hack the defense turrets
-the turrets destroy the defending combine fleet
-the protoss fleet enter, destroy rest of the defenders
-the main combine force launches a counter attack
-the player controls the protoss and the ued strike team. has to deafeat the combine
Also, I forgot to mention earlier, they have to take that space platform to get to the warpzone so they can jump to the next part of the sector.
Next missions will be:
and in the future of the story
As I already said, the story is in early stages. Sorry if this stuff sounded really retarded and autistic, but I got severely drunk since writing my last post. I could probably explain this better when sober. Also, if you want it I can upload some of the maps I made.
