in game music

mob effect: freeze - now only slows mobs down
  all freeze effects are about 50% longer

junk tech: music - adds background music to n-gon
junk tech: performance - adds fps tracker to n-gon

tech: dormancy - if a mob has died in the last 5 seconds increase damage by 50% else decrease damage by 50%
tech: torpor   - if a mob has died in the last 5 seconds reduce harm by 66% else increase harm by 33%
