Total Annihilation: Escalation 8.1.1 has been released. With it come numerous changes since the 6.8 release that was listed here on moddb. Here are the most major:
New player colors
'White' has been replaced by 'Pink', 'Dark Blue' has been replaced by 'Gold', 'Yellow' has been replaced by 'Orange','Black' has been replaced by 'Teal', 'Tan' has been replaced by a darker shade that is known as 'Maple', and finally 'Green' has been lightened up somewhat so it is more easily identified when near 'Teal' units. Minimap radar icons have also been changed for improved visibility.
New Construction Mobile hotkeys
Mobile constructors may now place certain structures via hotkeys, no longer do you have to rely on clicking the build icon to place them. Please, consult page 4 inside the help function ingame to see the hotkeys.
Enhanced Energy and Metal economy
TIer 1 and Tier 2 Metal Makers are now 25% more effective. Tier 3 Fusion Reactor energy output has been changed to 5,000 energy for both sides.
The Mobile Minelayers for both sides can now lay underwater Mines. Mines can also now be laid much faster due to instant buildtimes, however metal, and energy costs are unchanged so be prepared to have the resources necessary for laying them.
Hovercraft, on Tier 1 and 2 are in general cheaper, and faster to produce. T2 Hovercraft have had their firepower and/or armor improved. The Tier 3 Hovercraft have been improved with higher dps, and their weapons are now groundfire-based.
Improved Crawling Bombs
They have been improved so that they now pose a greater threat to Light Laser Towers, and to other ground units while on the ground. However, the Tier 3 Arm Vermin has had its armor reduced.
Tier 1 ground unit adjustments
Warriors now have more range, Stumpies, and Raiders are larger in appearance.
