I Finally got around to looking into half life properly, I chose the quote but i hadn't played the game,I kind of knew a bit about it and had seen people play it before but didn't really know the story line and the whole world to go with it. I was pretty much settled straight away on choosing Shirow and i think i chose the half life quote as they were both along the lines of 'Sci Fi' hoping it to be quite a smooth mix between the two in the end. 

Basically the general storyline is that Gordon Freeman ( working at Black Mesa as a scientist ) is testing portal technology which opens a portal between earth and another dimension called Xen, suddenly he is transporter and see a glimpse of the other dimensions seeing aliens from another world. awakening back at the research facility in the ruined test lab, finding that communications have been cut to the outside world has been cut so he needs to try and get to the surface but then discovers that the government is trying to cover the failed experiment up destroying the aliens that leaked out from the portal as well as the scientist at black mesa basically one huge massacre... the story continues from there but i wanted to focus on the black mesa facility and the scientists as the quote is centred around the scientists being massacred by marines and covered up by the government. so i want to keep this as the main theme when making my final piece.
