From the PlanetXbox360 feature editorial:
"Every single time a player snags another orb in Crackdown 2, they’re rewarded by a subtle audible tone in addition to visual cues denoting advancement towards the next level in whatever skill they might be filling at the time. While the activity may seem boring and even detrimental to the overall play experience according to some, there is very little denying that there is an addictive quality to nabbing another orb easily relatable to Pavlov’s psychology of classical conditioning. Ivan Pavlov, a Russian doctor and psychologist was the first to expound on the idea of classical condition through his theoretical research, which eventually found grounding in the scientific community. The essential basis of the training involves the utilization of neutral stimulus in conjunction with outside stimulation of significance."

Darren writes: "“XBOX NEEDS EXCLUSIVES!”. Sound familiar? It’s something that has been ringing in my ears since becoming an Xbox gamer nearly 20 years ago. It’s possibly the longest standing and harshest criticism levelled against Microsoft’s console family, and I can’t say I wholly disagree. However, there are some out there which can slip through the net every now and then. But bucking the trend was the original Crackdown, which was not one of them. It shifted a very healthy amount of units as well as drawing in universal praise from critics. A sequel then, would be a no-brainer."
It was basically crackdown 1 with zombies, was fun but corners were cut, solid game though.
Crackdown 1 was one of the underrated gems of last gen. I loved that game. Crackdown 2 was crackdown 1 with added zombies and gave the map a paint job. Disappointing, but still enjoyed it for what it was with the added wingsuit, toybox mode and 4 player co-op. Crackdown 3 was basically what Crackdown 2 should have been.

While it is unclear at this time whether its a glitch or intentional. Crackdown, and Crackdown 2 are now free for download on the Xbox store.

Crackdown 1 and 2 were both given for free to Xbox One users to celebrate their launch on the Xbox Live Store and backward compatibility support for the Xbox One. In addition to giving the games for free, Microsoft is now also giving the DLC for Crackdown 2.
Hunting orbs is one of the best parts of Crackdown 2 - until you get bored, they need even more Pavlov-like awards in the game....
isn't that true of every game? each time you level up or unlock a new gun it's an addictive little reward to keep you playing.
