Coming to the Zen Pinball 2 platform is, well, Portal! That's right, a pinball Portal game! Pretty cool, right? Take a look yourself.
This looks so cool to play, like holy crap! I'm gonna try my best to not fangasm, soooo *ahem*, alright.
If you love Portal, than prepare to have an orgasm on May 25th, 2015, in which it will come out on all version of Zen Pinball 2. Unfortunately, there's one platform that might be out of the loop.

There's no confirmation on it, but there's no clear answer on it coming to Wii U, despite the fact that all of other pinball tables on Zen Pinball 2 were released on the system. It seems strange why the Wii U would be out of the loop though
No trailer yet, but a few people have got their hands on it.
