Assassin's Creed Revelations -
(Memory 3-5 are straightforward on screen key combinations) Memory 6 - The Yerebatan Cistern is a massive, shadowy labyrinth that just so happens to be heavily patrolled by guards. This section goes smoothly until you're detected, so try your hardest to remain in hiding. Try to remain up in the scaffolding and take out your targets using ranged weapons like throwing knives and the crossbow. If you do not have these weapons yet, craft a lethal bomb using shrapnel and an impact shell.
