| —Old Plate Ruins description |
The Pulse Defense Module is a static device in Arknights, exclusive to Test Site #01 of Multivariate Cooperation: Defence Protocols, Old Plate Ruins.
As with other static units in M.C., the Pulse Defense Module consists of an upper part and a lower part. The upper player can deploy their units in the adjacent tiles to an upper Pulse Defense Module (marked by a lightning bolt like an L-44 Gramophone's Protocol Entries) to make it generate 1 SP every second per unit, with the friendlies having their DEF halved and Taunt. Once the Pulse Defense Module is fully charged, it can be activated by the upper player at the cost of 10 DP to deal heavy Pure damage in a radius of 3 tiles around the corresponding lower Pulse Defense Module and temporarily Stuns them, which is useful especially against Imperial Artillery Targeteers and Imperial Strikers.
