We were big fans of the original Civilization Revolution back in 2009, awarding it an impressive 5 out of 5 for its large amount of replay value, compulsive play, and surprising depth. We also said of this strategy classic that "you'd be hard pressed to find a better title in the genre". Strong stuff!

Five years on, and Civilization Revolution 2 has been released onto the App Store, and it's bringing with it some exciting new features for strategy buffs.

Among the new aerial units are Aircraft Carriers and Jet Fighters, and Special Forces also make an appearance.

New technology and building types also bring this streamlined version of "proper" Civilization closer in line with the PC original it's based on. Lasers? Check. Modern Medicine? Yep. Nuclear Power Plant? Sorted.

Scenario Challenges are also on-hand to provide a tactical puzzle to work through: you re-enact real-life world events to see how you fare against the world's greatest leaders. Think you can kick us Brits out of America all over again? Civilization Revolution 2 will find out for sure.

The visuals have also been given a spangly 3D overhaul. Here's hoping the sometimes cluttered UI of the first game has been fixed in the time that's passed.

The game is out now globally. You'll need a whopping £10.49 / $14.99 burning a hole in your pocket to purchase Civilization Revolution 2, and an iPhone 4S or iPad 2 (or better) to run it. Seems a tad on the expensive side, but at the time of writing there are no additional IAPs, so that's nice.

Will you be picking this up today, or is the price putting you off? Let us know, below.
