Lack of meaningful defence item's with ever increasing enemies make this almost unplayable. If it weren't for the badges I would have abandoned this after the first 10 minutes.
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!
Max gun and repair, then focus on max fighters for cover, then pump them up for the win.
I've never felt motivated enough to comment on a game before, but I can't believe how rubbish this is. The badges only make it more frustrating, because you can't tell how you are doing!
