I'm wondering: with Space navy and all that, will there also be a space airforce (kind of a silly question but still)? Anyway, here's a more detailed wave planning concept:
Wave 0: pilot Cuusoo set for testing of concept as a theme.
Wave 1: Basic wave, Gen 1 Space marine vehicles (current concepts) and singular Space navy fig(s).
Wave 2: Gen 1 Space marine vehicles and HQ, Gen 1 Space navy vehicles (basic ships), first Space army figs.
Wave 3: Gen 1 Space marine vehicles, Gen 1 Space navy vehicles (larger ships), Gen 1 Space army vehicles (turrets, heavy weapons).
Wave 4: Gen 2 Space marine vehicles (more advanced weapons and vehicles in general), Gen 2 Space navy vehicles, Gen 2 Space army vehicles (GIGANTIC weapons), Space marines special ops figs (purple).
Wave 5: Gen 2 Space marine vehicles, Gen 2 Space navy vehicles, Gen 2 Space army vehicles, Gen 2 Space marines special ops vehicles (essentially larger, more powerful and generally better versions of Space marine vehicles).
Wave 6: Gen 2 Space marine vehicles, Gen 2 Space navy vehicles, Gen 2 Space army vehicles, Gen 2 Space marines special ops vehicles.
