Yes, I downloaded the 1200 MS Point Metal Slug XX (updated version of Metal Slug 7) off Xbox Live Arcade today...

Impressions!

-I decided to play on Hard on my first playthrough. Horrible mistake... At least there were infinity continues.

-The smooth filter makes the backgrounds look like crap.

-Platform jumping?! Edit: I meant pit jumping.

-Pit jumping is tough to do, because you don't know when to jump.

-Holey crap, the second ceiling flytrap section in mission 4 is cheap as hell.

-The hit detection is... suspicious. I keep getting killed when bullets hit the ground in front of me. I even got killed by a bullet in mid-crouch. In mid-crouch! That animation appears for a millisecond.

-I can't believe the sleds can kill you in mission 5...

-The new, red robot enemy is incredibly cheap with its knife stab reach.

-A time machine that attacks?

-The giant mech slug was kinda cool, but you are soooooooo open to many attacks.

-Drill Instructor Cynthia babbles on forever if you choose to talk to her.

-No one was in online multiplayer the two times I checked. :(

-First playthrough completion stats: 38 continues used and only 5 POWs rescued. Ouch.

Thought it was better than Metal Slug 6. Then again, that's not a hard feat to pull off.
