Well, since its more than 3 years after the last englisch release (ignoring the rather unstable german 1.6), I think it's time for a new playable version.
But be warned - this is more a "test" version than a full relase. While most of the stuff should work fine, a couple of things (most notable the GDI Mastoton) are still not finished. However, these are mostly graphic problems and hardly affect gameply.
I also have to point out that the translation is not finished - while names and most of the desciptions are in english, a couple of them is still missing or in german. Still, it shouldn't be to hard to figure out.
However, you still have to install it manually and it might not work with the campaign mission, so use it at you own risk.
On the bright side, I now have access to a far better internet connection, so chances are TWA might be updated more often than once every blue moon.
