Hello Overhype,
Given how popular and cool the special crisis recruits are perhaps there could be some way to retain them for a donation/completing certain objectives etc?
Otherwise some players might not want to use these (excellent and fun!) characters much as they feel they’ll “waste” the experience these Brothers gain and then wonder off with.
Might be a cool reward for completing the crisis – chance to keep one of the backgrounds? Or the opportunity to recruit some?
