Right now in San Francisco there are many different versions of the new Mass Effect 2 game poster around town.
You can see the different versions here. What's so great about these giant posters is that they have a Microsoft Tag printed on them.
When a user scans the Tag, they are taken to a YouTube video that has combat footage from the game.

This is a great way to showcase new games to people who are out and about!

Try it out! Scan the Tag above and check out the game!
