During post-production of Gamers: Hands of Fate, one of the scenes called for an homage to The Matrix. Check out the breakdown of how the effect was re-created with cards replacing rows and rows of guns. While creating the effect in After Effects, a series of particle systems were used with just standard playing cards until the custom card art from the game itself arrived.

Music used in this video is directly from the Gamers: Hands of Fate OST which you can (and should) purchase here. It is pretty epic to listen to.
