Through your General, Animus33, you need to discuss with him how you are to split the 20'000 points throughout your Armies.
Now, in the original Apocalypse post I have put a link in with all the datasheets, hunt them down, and use them!
The enemy may have Defence Lasers, are you going to purchase a Starship to reign down Death?
These are the tactics you need to take on board!
Happy planning gentlemen, closer to the event time, the scenario and gaming board details will be released, with special assets for both generals.
Regards,
