Ezio swaggered into Assassin's Creed: Brotherhood with the look of an older, well-seasoned Italiano, demonstrating Ubisoft's first step nudging their assassin mascot through his life cycle with the help of a few physical changes to his character model. Now a cross between Christopher Lee and Jason Statham, in Assassin's Creed: Revelations his age is more telling but the maturity is equally notable in the new mission-types that have been introduced.
Since the introduction of assassin recruits, the Mentor position he had in Brotherhood is expanded. Assassin recruitment is still as available, but Ezio's role as head honcho is more clearly defined than in Brotherhood.
Now, in the newly devised Tower Defence sequence, he has Field Marshall-like technique and directs his underlings to attack from strategic spots along a gauntlet. It's an interesting change in pace when, while Revelations still continues Assassin's Creed's legacy of being 'that parkour series', in "Den Defence" Ezio commands units from a completely stationary position on a rooftop.
His abilities are limited to shooting enemies moving toward the entrance of the den. Similarly, he can control the aim of cannons held in the base, a feature clearly evolved out of the residue of Brotherhood's early cannon fight. While Brotherhood experimented with first-person cannoning, Revelations' is thoroughly a strategic affair which gives you a rooftop view of the available area to bomb. This becomes your primary offensive tactic when the final wave of enemies meanders in with a battering ram to break through your fortifications.
Barricades can be set up along the path as a defensive measure to keep incoming units out, but these degrade when attackers begin batting them down by hand. Thinking offensively, you can choose from a number of Assassin sub-types which each have different skills. Riflemen are a high-damage class but slower than Crossbowmen, and further classes like Air Assassin units unlock later on.
