"Defend yourself" is a mission objective in Sequence 11 / Memory 01: Bottom of the Barrel
Walkthrough[edit]
The flashback will begin. Arno will find himself fighting against a number of opponents. It is a single opponent you will need to take on 4 more foes at once. Nothing there is going to help with parrying. Just watch for incoming attacks as respond as best you can. Things do not end well.
