Not entirely sure if it's legit, but I came across this free mobile game you can play on your mobile phone (or not, depending on the phone maybe)

Devil May Cry - Java Mobile Games

I've already played halfway into it, so I know a fair bit about it. The credits does include the 'Capcom' logo in it and it says it's been released last year with that copyright symbol, but I guess you want me to go about the gameplay instead (the imagery you can see for yourself). xp

It's not as fun or exciting as the actual PS2 games but it's based a little on DMC3, since the background and the demons in the first few missions are similar to the PS2 game, as well as the inclusion of Vergil himself.

The story's a bit messed up really, no linear path to it and you can't redo missions you've already completed, until you reach the end where you're forced to go back to the first mission, but you'll be able to complete new unlocked missions you weren't allowed to do (pretty confusing, maybe I'll get a picture of it or something).

The only weapons you get are 'Rebellion' and 'Ebony and Ivory', and the red orbs only increase its attack power by a little bit. The only moves you can do are shoot, slice, Stinger, High Time, & Helm Breaker, and the only cool combo you can do is High Time and shoot with Ebony and Ivory. At least it's easy to get SSS rank for damage....

In my opinion, it's only satisfying enough if you can't play DMC where you are, but not something you'll enjoy like the real games...
