The One and Only Achievement Guide

The Mirror Match is an enemy combat set available in the Armax Combat Arena. The enemy set has a single difficulty level. Defeating the Mirror Match set will unlock the "One and Only" Achievement.

Opponents
The match involves two waves. In each wave you will be fighting alternate versions of Commander Shepard, similar to the Mysterious Figure. The opponents are based upon the six Classes available to players, with combat powers and weapons to match. Each opponent has Shields and Armor defenses. Their shields can regenerate but their Armor damage will not.

Wave One features a Soldier, Engineer and Adept that attack together. Each one grants 500 points upon defeat, but will respawn once each. They have the following powers and weapons:
 * Soldier - Frag Grenade, Carnage (power).
 * Engineer - Combat Drone, Incinerate.
 * Adept - Warp.

Wave Two features a Vanguard, Infiltrator and Sentinel that attack together. Again they will each respawn after being defeated. They have the following powers and weapons:
 * Vanguard - Charge, Nova.
 * Infiltrator - Tactical Cloak.
 * Sentinel - Tech Armor, N7 Hurricane.
