This week ended the first playtest of Extreme2, my Civilization IV mod. We concentrated on the latter half of the game, making sure the balances of cavalry, infantry, armored vehicles, ships, and planes were appropriate and worked well together. We ran into some graphic bugs, but got those fixed.
I am happy to say that I have added many new models including several new ships, three new buildings, and reworked civics.
I have added many Unique Units too, including a couple for the French, British, and Americans.
Here is a picture of an added Walrus/Seal Resource added to the game:
