Didn’t have a chance to get a first-hand look at God of War III at E3? Well, you’re in luck. Tune in to G4TV tonight at 6:30 p.m. (Eastern/Pacific) for X-Play‘s biggest demo ever (seriously, it goes more than 20 mins!). God of War III’s Game Director, Stig Asmussen, will not only walk us through the entire demo, but provide insight and commentary.

Don’t worry if you get caught in traffic, G4 will be replaying the episode again at 8pm. And if that still doesn’t work for you, you can watch the demo in HD on G4tv.com minutes after X-Play starts. You really have no excuse not to see this!

For more information, check out G4′s excellent (and prolific) gaming blog, The Feed.
