N7 Demolisher Engineer [Gold, White Hazard, Reapers]

Weapons: Cerberus Harrier Assault Rifle 10 with Armor Penetration/Weapon Damage and Clip Capacity Mods. Equipment: Incendiary Ammo 4 Assault Rifle Rail Amp 3 Power Amplifier 4 Grenade Capacity Match Settings were Gold/Unknown/Unknown. I play the Demolisher as a purely offensive class, completely forgoing the Fitness tree and focusing on power damage. This allows me to carpetbomb the map and detonate primed explosions with Arc Grenades and debuff high-health armored units with Homing Grenades. The Harrier has some decent punch, allows me to quickly kill bosses and other enemies whose shields I previously took down with the Arc Grenades. With the Incendiary Ammo and either Arc Grenades or Homing Grenades, I can create fire explosions; which are the best type of tech explosion in general because they panic organics and are very effective against armor. Sacrificing the entire Fitness tree will make you very squishy and you need to carefully watch your surroundings so you don't get spawned on and shot in the back, because you will die very quickly to a single enemy shooting you.
