Power Cap

We can also expand power capacity by feeding Originium Orc into Power Banks, will be doing this until we can produce enough batteries to sustain a larger production line.

This video guide show the various ways to have cheap and stable power in all stages of the AIC factory production.

Earning Stock Bills For Base Expansions

We can sell products to refuge camp site bases as we unlock those during the Main Story Missions. We can also be earning extra stock Bills via trading Elastic Goods (Unlocked From Upgrading Stock Redistributor) and Completing Daily Supply Depo Delivery Runs (Unlocked From Depot Node)

Here is a guide on the most efficient Valley 4 Stock Bills daily farming routes.

We can also earn bonus Stock Bills by assisting friends 3 times a day make up to 930,000 extra stock credits daily using this method

Mid-Game Progression

Continue to unlock more refuge camp side bases by progressing in the Main Story, establish Battery Factory or Buck Capsule factory depending on what the particular side base like the most

By choosing the Select goods option in the regional develop window we can see what each base want the most, at the current development level, this will change as side base level up, and so will our primary produced goods for this base.

By trading with side bases and selling goods, we can gain development experience and level those bases up to maxed level 4, make sure to do the side base missions as they reach the next level up threshold.

Expanding Bases Size & Bus Depo

Once we have earned enough stock credits via sell goods & daily AIC routes, we can expand our Main Base & Side Bases at the Steward NPC (make sure to see the Endgame Goals before overly expanding on particular base too much)

Goals For Endgame

We want to be making 18 HC Valley Battery + 18 Buck Capsule (A) Per Min In The Endgame, Also Other Materials & Plants Are A Bonus.

Transition To Endgame

The minimum requirement for our Valley 4: Endgame Blueprints Are:

• Main Base Size Full Expanded, Fully Expand One Line of Bus Depo

• Side Base Size & Bus Depo Expanded At Least Once
