Crackdown 2 is a third-person shooter featuring open-world, sandbox style game play. You control a genetically engineered agent assisting the Agency in the battle for Pacific City against a terrorist organization known as the Cell, and you're also tasked with keeping the run-down city clear of mutated freaks.
After a brief tutorial to give you an introduction to the controls and gameplay, then a couple of missions to introduce you to the main elements of the game, you're then left on your own to roam Pacific City and play the game as you wish. In order to complete the game you are tasked with activating beacons which destroy the freaks. You can also attempt (optional) Freak Breach and Tactical Location missions, which net you additional weapons and experience which go to improve your characters strength, agility, weapons skills, explosive skills and driving skills.
The beauty and curse of Crackdown 2 is that you're left to your own devices for most of the time. The beauty is that you can do the missions in any order you wish, or you can ignore the missions and do any of the optional activities in Pacific City, such as stunt jumps, running races across buildings, driving challenges etc etc. The curse is that there is virtually no storyline, and what little snippets you do get are from collecting the many audio tapes left lying around the city. A player could miss all the audio tapes and really have no idea of what is going on in the game, apart from the information given right at the start and right at the end of the game.
Much has been said about the similarities between Crackdown 2 and Crackdown 1. They are virtually the same game - the graphics in Crackdown 2 have received a slight polish (although it's still never going to be winning any beauty contests), the game is set in the same city and everything `feels' the same. Although it's quite interesting to go back to Pacific City and see it in a state of disrepair, it does smack of laziness on the part of the developers. In contrast, Saints Row and Saints Row 2 were both set in Stillwater, but SR2 never felt like it was a rehash of the prequel. There are some differences, some for the good and some for the bad. The good additions include wingsuits, the ability to pilot helicopters, 4 player online co-op, and being able to `ping' orbs, whereas the bad include non-morphing cars and the lack of any storyline or `enemy' that you have to bring down. The first game had you targeting gang members to bring down a crime ring, whereas in Crackdown 2, there is no real `enemy' apart from the hordes of freaks, and not much sense of achievement when you beat the game.
In the end, I really did enjoy Crackdown 2. It had me completely hooked for a very enjoyable fortnight, and I played it when I had any spare time. The game is great fun, blowing stuff up just never gets boring and hunting for the different kinds of orbs is both addictive and rewarding. The game really lights up if you can get a group of players together for some online co-op action, but it's equally fun running around the streets of Pacific City with a homing rocket launcher being told off by The Agency Voice for blowing up peacekeepers!
