Catalyst spraying

The catalyst spraying is the second clan support unit available from the Special Arms Factory. Once the Special Arms Factory has been built by a clan, all clan members can use it to build catalyst spraying in the same way as you produce normal supports (although it comes in batches of 3). If you leave the clan, any clan supports you have produced will remain in your inventory, but they cannot be used until you join a clan again. (Upgrades also depend on your clan.) To produce a batch of three catalyst sprayings, you need 200 ammunition, 1 biological waste, and 6 gas flasks, and it will take 3m. These resources can be obtained by completing the Operation "Unloading" clan expedition.

The catalyst spraying works similarly to healing, but rather than all of the pulses taking place at the same location, they are spread out over a larger area. Initially, the catalyst spraying has 3 healing pulses, with the radius of each pulse relatively small. The number of pulses, radius, and healing of each pulse can be upgraded at the Special Arms Factory.

The upgrades available at the Special Arms Factory are as follows. As with other clan purchases, all clan members can contribute towards the cost of an upgrade. Unlike most support upgrades (but like most ordinary research), each upgrade has multiple stages that contribute.
