PvP is a joy, but both equipment and to a lesser extent skills make a big difference compared to other PvP shooters such as Global Agenda. You won't be able to leave the prologue and dominate when you're against people with fully automatic weapons and plenty of damage reduction on their equipment. Once you're on a similar playing field, though, the variety and challenge of the PvP is satisfying.
Grouping is a mixed bag unless you BYOG. Joining most scenarios will throw you into a game in progress with people who, if you're lucky, will watch your back a little, and more than likely will completely ignore you. There is an auction house to interact with players indirectly and make cash, but the fees are fairly high unless you pay to subscribe.
The first episode of BLEEDOUT is free. Successive episodes weigh in at $2 each, and there is a subscription option to gain access to virtually everything in the game, so the end result is a system that resembles an episodic DDO. While the quests and especially the atmosphere of BLEEDOUT are top-notch, the episodes themselves are not worth the price tag unless you truly enjoy the intros and hand drawn comic book style. One of the ten episodes is released every week or two, so expenses will pile up quickly and you don't know if you're going to enjoy the direction of the story or, more importantly, the gameplay mission associated with it before your purchase is finalized.
CrimeCraft is a solid time waster for fun PvE and PvP on the fly, but it requires a fairly large time investment (both in terms of skills and equipment) in order to become competitive. It's being updated fairly often, but the lasting appeal to you personally will increase the more time you put into it. The prologue is singularly painful, but if you make it and get into the actual game and enjoy it, you'll likely stick with it for a while.
BLEEDOUT is very well done and executed, but with a big emphasis on the storyline, the lasting appeal of the game is crippled when you know what happens as you play through it on multiple characters.
It takes a lot to make a shooter MMO work, and CrimeCraft does a respectable job of it. It's receiving considerable support, with episode 4 of BLEEDOUT now live as of Christmas. PvE and PvP are quick and easy to get into, and quests are readily available at any given point in time. If you can overlook the flaws of progression and pacing, you'll find a respectable online shooter that has zero up-front cost, and also has a polished film noir feel if you choose to progress into the episodic content of BLEEDOUT.
