This is a BP for the pre-blueprint science hub. This is not 'really' a blueprint, as you will not have unlocked blueprints yet, but this is generally how the earliest game assembly should look like.

In this phase the sciences have an item cost and most things are handcrafted. General strategy is to keep the mecha crafting ever higher tier items. Make sure you build more windmills as you unlock smelting.

For max difficulty: you must unlock combustibles asap. Use the hydrogen fuel rods to increase mecha recovery during the first wave of attack. Use armor customization to reduce mecha power usage in between attacks. When you are ready (10 minutes in), craft 4 more assemblers and make sure you have enough materials to unlock combustibles and blueprinting.
