This is wayyyyy geeky. Portal 2 is a first person puzzle platform, sci-fi video game with a backstory that centers around Cave Johnson, the head of Aperture Science. This is like a game within another game because it is set in the Half-Life universe. So many things go wrong in these labs: poisoning from neurotoxin and many other very geeky things. Wow, I love gamer shirts that only other serious gamers would understand. Beautiful! But then again, I am a very big geek.
