Firaxis has just updated its free WWI air combat simulation Sid Meier's Ace Patrol with a bunch of new content, including new missions.

In fact, this update contains 60 completely new assignments.

In these new missions - which span the game's four nations (Britain, France, America, and Germany) - Firaxis introduces several new mission types.

Fire up Sid Meier's Ace Patrol after downloading this update and you'll be able to jump into the cockpit of several bombers and reconnaissance planes, for example.

In other missions, you'll be tasked with taking down squadrons of fighters on your lonesome, and destroying heavily guarded key targets.

At review, we handed the barrel-rolling Sid Meier's Ace Patrol a Pocket Gamer Gold Award.

Our Harry called it a "brilliantly balanced, perfectly playable game of strategy and swooping turns that will have you enthralled", and noted that it's a "must-play" title.

You can download Sid Meier's Ace Patrol from the App Store right this second for free.
