Eurogamer did the comparison, it seems that PS3 version is slightly better than 360, with better colour range and no screen tearing, but 360 have more stable framerate (but not significantly) Both version are very good http://www.eurogamer.net/articles/digitalfoundry-vanquish-demo-showdown-blog-entry (Sorry for my bad english...)

This game is full of awesome.

Totally my style of game.

TPS, Explosions everywhere, flashy action, high speed boosting, great gunplay and gameplay overall. The right ingredients are there.

Just a few things though that I didn't find too happy with.

No jump button. Melee attack using up all my gauge.

Other than that, can't wait to play the full game next month :D!!!

Holy Shit! The demo was pretty amazing. I'd recommend that everyone goes through the tutorial though, I didn't the first time and I was lost on the controls. I'm surprised the game looks so good and can run so smoothly at the same time, it also destroys Uncharted and Gears when it comes to TPS controls. Mikami knows his stuff. (PS3 Version)

Afterall, he did create Resident Evil and made Resident Evil 4, the game that changed the way we play TPS games today.

just played the demo its pretty awesome. he dies a little easier than i expected but thats fine.

eh fuck my internet just capped again >_>

Good demo, nothing amazing but good.

Using the jet pack thingy is a lotta fun.

Did you play it the highest difficulty? Mikami games tend to be much better when they're put on hard. You should try melee alot more and use the slow-mo while shooting more often. If you've done all that then ignore me, but I enjoyed my second play through much more after learning everything I could do in the game. 

Amazing demo. Basically, Vanquish is to Gears of War what Bayonetta was to Devil May Cry. As far as TPS gameplay goes, this shits on everything else out there. All this stuff going on onscreen at such an incredible speed. It's impossible to take it all in.

This deserves to be a big hit for Platinum. Any shooter fan will love it.

I'm definitely going to get this game.  I didnt enjoy a demo this much since RE5.  Looks awesome and plays well.
