(Adept) N7 Fury: Throw, Annihilation Field*, Dark Channel
"Fury operatives use implants to fuel biotics and their incredible movement speed. These operatives wind an unpredictable path on the battlefield, moving in and out of combat before returning to unleash a sweeping biotic attack on their unsuspecting targets."
(Soldier) N7 Destroyer: Multi-Frag Grenade*, Missile Launcher*, Devastator Mode*
"The Destroyer's T5-V Battlesuit gives these strong-but-slow soldiers mech-like protection. Driven by eezo-assisted actuators, these frontline troopers carry heavy weapons onto the battlefield."
(Engineer) N7 Demolisher: Homing Grenade*, Arc Grenade, Supply Pylon*
"The Demolisher uses grenades to attack at range and to terrorize the battlefield. Demolishers can also create a supply pylon that stocks allies with an unending reserve of grenades and thermal reloads."
(Sentinel) N7 Paladin: Snap Freeze*, Incinerate, Energy Drain
"The Paladin carries a powerful omni-shield onto the battlefield to block enemy fire. The Paladin also uses the shield as a heavy-melee weapon that, when modified with incindiery or cryo upgrades, creates a devastating combination attack."
(Infiltrator) N7 Shadow: Tactical Cloak, Shadow Strike, Electric Slash*
"Shadow infiltrators use implants to dramatically improve agility, making them slippery combatants on the battlefield. Their monomolecular blades are a menace from cover and close range."
(Vanguard) N7 Slayer: Phase Disruptor*, Biotic Charge, Biotic Slash*
"Slayers use implants to dramatically improve mobility. Their dizzying sword attacks can hit multiple opponents, and the Slayer's ability to slip fire makes them hard to pin down on the battielfield."
