Just tried it the first time. One problem jumps out instantly. Its not a BIG problem, but it does mean that it is an impossible level for Germans.
The Australians are given a command to defend the first base. For the first few minutes, it isn't a big issue, but then if the Germans don't cap that base in that time, it becomes a stronghold of no less than 30 Aussie bots, most wieliding SMGs as per their AI logic to defend against bots coming in at close quarters. The Germans on the other hand, come from range, most with rifles...
I think if the initial assault was split between that base and the tempe almost equally, Aussies will defend either and be more uniformly spread out.
There is also an oppotunity for a flanking maneouver since the base next in line also can be capped. This means, Germans can then cut off that first base if it initially proved too hard to cap, and deal with it peace-meal, since not all defending bots wil be spawning there, but coming from the rear bases.
I do like the fact that bots seem to use stationary positions alot more now, and the defend orders means, allied aircrafts are available for close air support from the get-go.
