Notes

• The Rat Pack is a special drop and requires a Lab Rat to be killed with blunt damage while still trapped using a Net Launcher
  • Blunt weapons with effects can be used.(i.e. Thermal Mallet) However, the chances of succeeding are lower since the Lab Rat will likely die from the effect instead of blunt damage.
