I've been playing this for a while, and have only a few achievements left. Mostly I'm starting to wonder if "SO SRS" can be glitched, because I'm pretty sure I have killed 10K "things" several times over. That's assuming the achievement is cumulative, and not one that requires a very long game of Endless Zombies...
Also wondering if "Invincible Viking" also means a perfect game, or if it only requires surviving the duration of the actual "boss battle" against the moon without dying.
