I'm happy to announce that I'm finally finished with rebalancing the mod. I just did some testing of my own to see how matches would play out against a normal NEXUS AI, and while the AI doesn't yet seem to take advantage of any of the new stuff, allowing me to steamroll it quickly, before I'm able to research into T2 technology, I'm kind of pleased with how everything works.

Of course, I'm just one playtester, and I'll need other playtesters to help fine-tune this mod.
However, I still have one more thing that I need to do before releasing this for open beta-testing, and that is to create a few more models that would give each of the new turrets and structures a more recognizable appearance from eachother. Here's a picture of what .pie models I used for all the Howitzers:
On the left side of the screen, from left to right, starting from the top, we have:
the regular Howitzer; the Heavy Howitzer (which was formerly called the Ground Shaker); the Rotary Howitzer (which was formerly called the Hellstorm); the Incendiary Howitzer (now with a new look); the Heavy Plasmite Howitzer (which requires Plasmite Flamer as a prerequisite), the Rotary Plasmite Howitzer (which also requires the Plasmite Flamer); the Sureshot Howitzer (a howitzer that fires anti-tank rounds that home in to their target); the Heavy Sureshot Howitzer; the Rotary Sureshot Howitzer; the Ground Shaker (an anti-structure howitzer that fires shells designed to create miniature earthquakes to damage structures); and the Gattling Howitzer (which requires some research into the Machinegun line to unlock).
On the right side are railgun versions of those same Howitzers, with much longer range, and dealing more damage than their lesser counterparts, while fulfilling the same roles. They will, however, require the Needlegun as a prerequisite in order to unlock, so they won't come easily.
By the way, all these Howitzers are mounted on different bunkers with different levels of durability. Some are mounted on Supercrete Bunkers, others are mounted on Plascrete Bunkers, and all the Gauss Howitzers to the right are mounted on Plasteel Bunkers.
I've also done some work on some new Howitzer Firebases:
From top to bottom are the regular and Gauss Howitzer Firebases, the Plasmite Howitzer Firebases, and the Sureshot Howitzer Firebases. Now, while the more advanced firebases would also be more durable, I've yet to work on giving the firebases different appearances.
Finally, I've decided on a name for this expansion pack: Warzone 2100: Contingency.
