I have tried a few times now to get the detox trophy but with no luck. Does anyone know how this is unlocked? I appear to get toxic rain from one of the planetary missions but that didn't seem to work....any ideas welcome.
Having tried a number of times I am slowly losing the will with this trophy. Can anyone offer any advice as to how to do this? I make it to the top but no trophy. When does the timer start? Any help would be grately appreciated
