Tip for hard badge: Throw kitty at the green aliens which shoot fireballs to get them off the platform (when kitty is attacking, they move really fast) and then die before the alien does. This doesn't count as a kill and can remove them pests from vital locations.

Really good, you can beat the boss with this.
Use infector first against boss, this keep firing the beam. Off screen enemies the boss spawns will have an arrow, just use the laser to kill them.
