Not to thread crap, but its been around this price for about 3-4 years now.
[quote name='Cheeseknight28']I was going to burn $9 on this and get some quick achievements a few days back but I did some research and you only get 280 for beating single player... and that's only if you do runs on Agent, Secret, Perfect, and Dark difficulties. Oh and you have to do them all again on co-op.
Multiplayer consists of endurance achievements, 10/100/1000 of everything. So if you are thinking you'll get quick achievements on a launch title when they didn't know how to be creative, pass on it. They are a PITA.[/QUOTE]
Dark agent is insanely difficult. No health, no continues. Nothing like spending 30-45 mins on a level, just to die at the boss fight, and start all over.
