I know I made a Anti-Leader tips thread so this is how to fight back as a scientist. Weapons: Photon burst rifle: Good at any range but runs out of ammo quickly. EMP shotgun: Can kill a leader with to shots. Energon Repair Ray: Good close range weapon. Can be used as a attack weapon. Neatron assault rifle: Sort of the standard weapon and theres the burst rifle and the shotgun instead. Abilities: Shockwave: Can be upgraded to take away 1 1/2 bars of health away I think. Disscise: Good with damage buff but don't get to close to enemies. I see this mistake a lot. Don't use Air-raid and Shockwave for this ability their easy to spot out. Spawn sentry: If you upgrade armor. Drain: If you upgrade heal rate. Perks: You guys choose. Also you can heal yourself with the heal grenades. I would recommend picking up a Null-Ray or a X12 to improve firepower. I would give to shock cannon to a leader or soldier because even with a Over-shield your not going to be able to do much.
