Memory 2: The Arsenal Gates

First things first, you need a crowd! Head to the heralds and bribe them to gather up a large group of rioters. Make sure you don't accidentally wander into the small restricted area in the middle of the plaza, or you might scare them off before the main event even starts.

Once you've paid off the heralds and have a decent crowd, head to the objective marker to kick off the fight.

During the fight, your priority is calling in your Assassins. Try to use only one Assassin Signal for the first wave of enemies. It's crucial to keep an eye on the rioters; if you lose more than 4 or 5 early on, hitting that 40+ rioter goal for full synchronization will become a real challenge.

When more enemies show up, especially those wielding pitchforks, it's time to unleash the rest of your Assassin backup.

To help keep your rioters alive, use poison on the enemies to slow them down, and use ranged bombs to stun them. This gives your allies a better chance to survive.

Don't get tunnel vision! Try not to get bogged down fighting one guard or group while the others are busy taking down your precious rioters. Keep an eye on the whole battlefield.

After the gate comes down, you'll watch a cutscene. Be ready, because another fight is usually right around the corner.
