Noticed a rather convenient glitch today lol. I had just collected 8 blast shards to unlock the final upgrade of the phosphor beam. So after collecting my next shard from a drone, I suddenly gained 35 shards all at once.
I went to start a new game and it loaded me into seattle with no missions, no DUP billboards, but everything else to collect in the game. I had all the powers but had to get all the blast shards to upgrade and i was listed as a vandal. Pretty fun if you just want to run around and do all the collecting, but no idea how it happed. I think it should be an option to just screw around like that and i'm never goint to delete the save for it lol.
