All base modules upon destruction inflict damage to all adjacent modules, this includes modules directly north, south, east, west as well as diagonally. The damage they inflict varies greatly, see specific pages on the base modules for the exact amount of damage they deal upon destruction.
The damage they inflict cannot be mitigated by Metaphase shields, they will suffer full damage from explosions.
Collateral damage forces the base defenders to spread out their combat modules, particularly away from other high level combat modules and especially away from the bridge or the fleet bay as those tend to have very high amounts of collateral damage.
Collateral damage does not damage ships, squadrons, wings or Terminus mines. Heavily damaged, compact bases still repairing after battle or bases with low armor can be destroyed quickly as collateral damage can set off a chain reaction of explosion, destroying large portions of the base at a time.
According to what Kixeye CM CarterGee said on the offical update thread :
"Base modules have large amounts of energy passing through them to keep them functional. During combat as modules are destroyed, explosions occur that can affect nearby modules. As a rule, the higher a module’s base health the more energy it requires to keep operational, resulting in heavily fortified combat modules being particularly volatile. It is intended that players adopt new strategies for base layouts to avoid potentially disastrous chain reactions if their opponent breaches their defenses.
- Exploding modules deal explosive AOE damage
- Damage only affects modules directly next to the destroyed module.
- Damage is dealt on a per module / level basis
- Adding shields or armor will not result in a bigger boom, but modules with a higher base health like the Shipyard will cause more damage than a resource generator. Within each module click “View Components” to view collateral damage."
- Upon introduction, collateral damage was met with negative feedback.
