Tip to own Nekon Atack
INFINITE Bonus (skill shop)
Lock Bonus (skill bar)
Blue Laser (weapon found in level)
or Fusion Synth (Fusion Fire+Phase Synth)
The Z900 (upgraded, but not necessary)
Stun (skill)
Magnet (skill)
Mega-Blast (skill)
Warp Speed (skill)
Relentless Strike (skill)
Simply spam your 5 skills, and use your Weapon to wipe everything out, the Mega-Blast is to just speed it up a little to make sure you get the win. You will never run out of Energy, even spamming the 5 keys every few seconds. With all this, you should be getting 11-12 Orbs every second, and will complete each Nekon Attack first try.
