Haven't found 'em all, however, we are working on it, me and my friend that is, on both games, mine and his
And on his one, we've searched the bottom half of New York, more ess from a few blocks south of Central Park and he's got at least between 70 to 80 gamma and the same for the furry canisters, not sure on the exact number.
But yeah, hard to find them if the strike teams are after you, since the music changes....next time, gonna start searching the other half as he had found like 60 odd canisters, well 60 gamma and 60 furry before we went to the map.
