People were once so excited about Hawken. It looked awesome, it had a wonderful visual design to it, and then... well, then it went free-to-play, and it didn't have singleplayer, and that kinda took the wind out of a lot of people's sails. A shame, but hey, the game still looks great, people are playing it, and the art still looks as good as ever.
The pieces you're about to see come from the team's continued work on the game, in particular a new map called Wreckage. Artists involved include Khang Le, Nhat Nguyen, Brandford Miles Williams, Wesley Griffith, Darren Quach and Jon Lee.
