Chell is you, you are Chell. You explore the labs together as the test subject, a silent protagonist that actually has more presence than a lot of TV characters.
Portal merchandise is mostly robot-oriented. GLaDOS and power cubes and the like, but this minimal design finally gives us a Portal Chell shirt.
It reminds me a lot of 80s films, the colors are very Blade Runner and there’s not a whole lot of video game shirts you could wear to a black tie dinner (don’t quote me on this when you try it out…)
