COD4 mass effect edition. (Or how to Demolisher)

This class will get you your grenade damage challenges done VERY quickly.

You will need

N7 Demolisher

Grenade Capacity V

Power Amplifier Module

Incendiary rounds

A shotgun of your choice.

My exact build.

Enemy preference - None. Though Reapers is the most fun for me.

Playstyle

Sit on top of your pylon and shoot at a target. Throw arc nade at target, then follow up with a homing grenade. Replace your pylon whenever possible to keep nades topped up.

The reason this works so well is because the target is set on fire with the incendiary rounds. The arc nade will detonate a fire explosion if it kills the target, and if not, will prime a tech burst. The homing grenade will detonate that.

When you are looking to GTFO, spamming arc nades works a treat, and will often shock or kill most enemies after 4 have been thrown in quick succession.

Hope this helps. Have consistently gotten scores of over 100K using this setup. Also is very potent on platinum as the scaling of power combos makes fire explosions and tech bursts extremely deadly to any surrounding mooks.
