Zen Studios has released an image teasing some kind of partnership with Valve, presumably entailing either a new pinball game or content for one of its existing games.

The image below is all we have to go on at this point. There don't appear to be any Easter eggs lurking in it, waiting to reveal the details of what the project entails.

Zen has released numerous licensed standalone pinball games in the past, as well as DLC tables for its latest pinball games, Pinball FX 2 and Zen Pinball 2. These collaborations include the likes of South Park, Star Wars, and Marvel.

Valve has no shortage of properties it could lend to a pinball project, with the big ones being Half-Life, Portal, Team Fortress, Left 4 Dead, Dota 2, and Counter-Strike. There's also the more obscure stuff, like Alien Swarm and Ricochet.

What do you think this will turn out to be? Let us know in the comments below.
