This is both an advantage and a disadvantage, just like the Maginot line itself was.Īdditionally, the AI will just straight up not attack forts that are too high of a level (around 6 or 7), which while that does wonders for preserving your stuff, it isn't destroying enemy stuff either. Any civ IC spent on building forts when you never sit in those forts and get attacked is stealing from your equipment production.įorts also don't move, so the enemy can simply choose not to attack your forts and go around them, much like how the Germans infamously ignored the Maginot Line. That amount of civ IC could be used to build a lot of factories that could build a lot of guns or tanks.Ī reason not to build forts at all, is if you have such a technological, industrial, or doctrinal advantage over the enemy that you don't need to really defend yourself, you just need to push them out of the way and grab their capital. This goes all the way up with level 10 costing 5000 IC by itself, or a cumulative total cost of 27500 IC to go from 0 to 10. But going from no fort to level 2 fort costs 1500 IC. So, building a level 1 fort only costs 500 IC.
#HEARTS OF IRON 4 FORTS PLUS#
Reasons not to build level 10 forts, is that it costs 500 IC plus another 500 IC for every level of fort already existing on the same tile. As a by-product it also means that you need less defense stat in your templates and can shift more of that width into sources of attacks, and be better able to punish enemies for attacking your forts. Reducing enemy attack instead of just boosting your defense, means that you take less damage and you lose less stuff.
Building beyond 6 or 7 helps you maintain the fort bonus longer. So, going beyond level 6 or 7 forts seems useless, except that flanking a fort reduces its level by 1 to a minimum of 1, and forts can be damaged to reduce their level.
At level 10 that would be -150% attack, but its capped at -99%. Forts reduce enemy attack by 15% per level.
