Assassin's Creed 2 - No-hitter

Well I said that the no-hitter trophy in Assassin's Creed 2 would be the most difficult, but didn't say why.

Kill 10 enemies while remaining in combat without taking a hit; sounds simple enough why the hassle? Well the guards roam in groups of three so you have to lead one set to another and they tend to cluster in packs of... three. Manage to find 12 and you can guarantee that 3 of them have set up across an alley to cut off your 'escape'. Kill the set chasing with you and the combat will end because these three aren't engaged with you.

Better yet the best way to avoid being hit is to block and then counter - an insta-kill; however show too much flair and some of the guards will, quite rightly, run away fleeing for their lives; bringing the total below 10. So what to do?

Well tips include killing the monks who become hostile, um no I think not; or using smoke bombs; again not my style. So how to remain in 'proper' combat and get the trophy - Lorenzo de Medici. During the assassination attempt in sequence 4 there's around 12 guards, you remain in combat mode, they won't run away, and as a bonus there's no innocents around and plenty of space. Double bonus if you get hit you can just abort the memory and start from scratch it's only a single cut-scene away. Excellent
