The current pre-release of the client ("pioneer" in the version) is only compatible to itself. So you can only play with other testers. Please be aware!
I made 5 engies, 2 land scouts, then immediately started t2. flak deals with the t1 bombers wonderfully (you have to dodge though) and mongoose can deal with rhinos better than pillars. while mongoose stave off the small armies the acu can upgrade. didnt make a 2nd factory until like 10 minutes in
