Overview[]
In Collapse Mutation, players were tasked with eliminating enemies using their T-Doll player in the dedicated event mode. Players were able to produce additional T-Dolls and upgrade their manpower, ammunition and their dedicated rations and parts. By doing neural upgrades to a T-Doll, would allow them to have additional skills that aid the player. In doing all the above, players could earn rewards in two dedicated reward pages: Kalina's Rewards and Exoverse Rewards.
