I know that. it was a development test. When you see on the game page a built with a "b" on the version name is a testing one. For example 15h ago it was "0.5.4b". The current one "0.5.5" is a stable one.
Every time i write all new features at the bottom of the page.
New Features:
-New german medics.
-New voices.
-Lot of fixes.
-Big performance improvement.
-General fixes.
This time is a little update, because i am working on a totally new AI to make mission more funny (and easy to create, so new missions will added more frequently)
