Makes partial cover count as full.

– In-Game Description, XCOM: Enemy Unknown

XCOM: Enemy Within[]

Low Profile will also make partial cover count as full cover for the purposes of Mimetic Skin, allowing for the Sniper (or other class if the player is using the Training Roulette Second Wave option) to be a highly mobile scout for the rest of the party. This combination also synergizes well with Snap Shot and In The Zone, since it allows the Sniper to flank enemy packs while remaining undetected.
