Some gameplay footage from a live streaming event.
It's an hour video, with a 4 minute countdown at the start, so fast forward past that.
They go through the set up of the game, so skip to about 15 minutes for game-play.

It looks like fun, but I think that if you don't spend (a lot of) money on the upgrades or VIP packs, it won't be much fun being out-classed and being unable to defeat those who did buy the upgrades.

Then again, nothing should be a free handout in life (people need to earn what they get)... it all has to be paid for by someone, and there has to be some sort of incentive to pay for its usage (by giving you a fairer chance at winning the games if you do give them money).
