Mindlog, don't forget those pictures and descriptions!
Fury Adept:
Fury: "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."
Destroyer Soldier:
Destroyer: "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."
Demolisher Engineer
Demolisher: "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."
Paladin Sentinel
Paladin: "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."
Shadow Infiltrator:
Shadow: "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."
Slayer Vanguard:
Slayer: "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."
Also, new gun pics:
EDIT: Quoted the pictures for size.
EDIT2: Apparently I messed up the Vanguard and Infiltrator. I would guess that the Vanguard's sword is biotic, whereas the "monomolecular blade" for the Infiltrators is tangible.
God, I want a trailer.
