Effigy of the Forgotten
Dude! You just completed the Effigy of the Forgotten achievement in Orbital Decay and won the Effigy of the Forgotten badge and 30 points.
How I did Hard mode; Upgrade gun dam and fire rate a few times, then I went for 2 fighters, repair a few times, max out the number of fighters and then cannon.
Also, later on, turrets are quite useable.
