plasma ball
  much more damage
  new graphics
  fast decay in mob shields
  works with capacitor
  some bug fixes

paradigm shift: 4->10% chance to give research instead of tech
harpoon density: 0.006->0.005  (lower damage and knock back to mobs)
wormhole: 7->5% duplication chance
pilot wave uses less energy
