*edit* (wanted to be sure they got in the tally, before someone ninja'd because I was still typing the following exposition)
Ah, how I loved running around Synd maps, my little zombie followers in tow. Chase down and zap 5, and you can turn police officers... zap more, and you can eventually swell the ranks of your backup operatives with enemy agents. I can think of only a handful of missions that could be failed when you have a quad of jacked up agents gathering every civilian in sight.
Mmmmm... I don't think I can count the number of farms that were reduced to charred cinders after the comms squawked "CONTACT"* and my entire team immediately opened fire with their spinning barrels of explosive death. Middle of the night and can't see if anything is lurking in that grove or wheat field? Swap to the yellow-band clip and see if anything screams like that cousin that seems to always forget that they shouldn't be holding the roman candle when they light it... At the very least, you'll have a few minutes of light as the fire spreads.
For all of the faults of AC1, I seemed to always forgive them, just because the stealth kills with Altair's wrist blade was so very cool. Fast forward to Ezio's time in the spotlight, and things just get better. No more need to just sit still and counter-kill with them, you can actually block, and even go on the offensive, if you've got the guts and your opponent has no armor.
