Homo Homini Lupus Est

Homo Homini Lupus Est is an achievement/trophy in the Faction Pack, a DLC for Metro Last Light.

Overview
This achievement is awarded for killing 100 enemies in one playthrough of the mission, Heavy Squad. The description says 'with heavy weapons', but all three guns Hans uses: the Hellbreath; the Gatling; the Medved - count as kills. The tank itself does not count as a kill (though the soldiers on it do) and the enemies continually running up the right side of the bridge do not either; only soldiers in the central bridge count. It is advised to take out as many snipers as you can, and delay killing the Gatling-gunner to kill more snipers. Use the Gatling on everyone else. If done correctly, this should unlock during the final wave, before the tank.

Trivia

 * 'Homo Homini Lupus Est', as translated from Latin means  'Man is a wolf to his fellow man', alluding to Hans' power and dangerousness.
