2K Games to unveild something BIG at PAX

 2K Games To Unveil Something Big At PAX] PAX isn't normally a place we expect to see huge video game reveals, but rather enjoy the ones that have been revealed. 2K Games is apperently looking to change that. So here's the scoop; tomorrow at 10am PST (1pm EST), 2K Games will have a live streaming of their announcement. No further details are known, but with a bit of speculation in the mix, leads one to the assumption of a possible Duke Nukem announcement. We won't know until early tomorrow. Stay-tuned. The live stream will take place here, or you can stay tuned to this page by bookmarking. Team Ironstar has you covered!

The rumours would appear to be true. Borderlands dev Gearbox IS working on Duke Nukem Forever - and the reborn game is set to be unveiled at Seattle event PAX today.

US dev sources have indicated to CVG that the game will get a "grand demo" at the show - and will be built upon what 3D Realms has already created, rather than a completely fresh project. We're hopeful it will be playable.
