I recently played (and loved the shit out of) Portal 2, I am a big fan of the original and the second is just as good. I especially loved all the advertising Valve did to promote the game, with well-designed and well-animated shorts/posters/etc. I was a bit surprised to see that the in-game packaging for the turret was so blah, which is understandable since it's an in-game graphic, no one gives a shit except design nerds. So I did fan packaging.
Holy god hard as hell, especially being that I had to come up with copy myself (newfound respect for copy writers!), and packaging design =/= layout design. I mocked it up, revised it a lot, had to mess with the colors, etc. Rendering was a bitch (not good at it at all), and I have inconsistent blacks and I think my computer is going to kill itself, but I'm fairly satisfied with the end result, hope you guys like it.
You can see a close-up of the panels here (and read the text, which I hope is funny): [link]
(sorry for the shitty link, it's the best I got)
Portal belongs to Valve. I'd recommend full-viewing it.
