If your units take too long to show up, check whether they are still in production or already on the road. To increase factory production rate in Ashes of the Singularity II, build additional powered facilities of the same type as the one making the units you need. If the units finish promptly and spend most of their time traveling, build closer to the army.
Add another facility of the same type
Start with the unit you want to recruit and identify the facility type it uses. Build another facility of that type in a region that can keep it powered. The developers describe the facilities working together to accelerate production across the map in Dev Journal #5 on the sequel’s production system.
For example, if you want to speed up production through your Vehicle Yard, add another Vehicle Yard. A duplicate of the right facility addresses that production pipeline. The journal does not give a per-building multiplier, so avoid planning around an assumed doubling of output.
Check the region’s power connection
Trace the route from the factory’s region back to your home region. If the enemy cuts that connection, the isolated region loses power and its production buildings stop working. A well-placed factory can therefore drop out of your production network without being destroyed.
Before spending on another building, check whether you can restore or protect a contested link. If the problem is that you cannot afford the orders you want to place, check your income before committing more resources to construction.
Decide where the next facility should go
The same building can address two problems at once. An extra facility of the right type speeds up recruitment, and a forward facility can reduce the distance new units have to travel. For reinforcements, the development journal says new units spawn at the relevant production building closest to the army. For a new army, the initial rally point is the reference instead.
Keep the facilities you built farther back if their regions remain powered. The production network can still benefit from them while your forward factory serves as a closer spawn point.
FAQ
Can engineers speed up an existing factory?
Assigning engineers to accelerate a building is described as a mechanic in the original game. The sequel’s production journal points to another facility of the same type for this purpose.
Why are my reinforcements still slow after I build a second factory?
If the units finish building but take a long time to join your army, look at the distance from their spawn point to the front. A closer powered facility is the practical change to try.
Does a factory keep working when its region is cut off?
The development journal says production stops in an isolated, unpowered region. Restore a territorial connection to bring the region back into the network.
