Half-Life 2D Creators Interviewed
Thanks to Gamers With Jobs for its interview with the creators of Half-Life 2D: Codename Gordon, a "Flash-made 2D shooter based on the Half-Life 2 footage that was shown so far", as previously mentioned on Slashdot Games. Dev team member Paul Kamma promises: "The game [will be released] before HL2", and a preview at City17.de has more information, including many screenshots of the multiple levels "inspired by the E3 [2003] videos."
...as it may be as close to playing HL2 as us Mac users are going to get.
Plus it looks similar to Metal Slug, which is never a bad thing IMO.
