Found 1x GA1 and 1x GA2 on random outdoor / rk mission mobs and 1x GA1 on some random mob inside foremans ages ago.
Found a GA4 nano on some bald clan engie ages ago... or well, he messaged me and asked me if I had GA4 or if I planned to use it if I got one... pretty sure he found it in a solo mission. One of my first friends in AO and one of few still active from back then. Great guy
