Up to three protections upgrades can be installed in each of the inventory and technology sections of the Exosuit. Installing four or more upgrades in a given inventory/technology section of the Exosuit will disable all upgrades of that type until the upgrade count is reduced to three or less. As a result, it is possible to have up to six of these upgrades in total, space permitting of three in each section.


The upgrades can be acquired from:

  • A Technology Merchant in a Space station for a variable price generally in line with the class of the upgrade. This is the most common and predictable/reliable way to obtain the upgrade module. The upgrade modules are always the same in given system space station, although they will only replenish if purchased after the traveller has moved on and visited at least three [ed. note: need confirmation on count] different star systems before returning.
