Gamershell is the latest website to preview Planetside. In my opinion, it's one of the better previews around. Here's a clip:
While I'm talking about coolness factor, let me tell you about one of my experiences. I was doing a little cross-country run between bases on a lark, and see movement in the distance as I am coming over a hill. I zoomed in with my scope, and see a full assault unit, including a "popper" (mobile respawner), MAX, troop transport and and air gunship. I was near a tower that had a turret on it, so I dropped below the ridge line (so I am out of sight) and run to the tower and up eight flights of stairs and hop in the turret. Amazingly, these guys didn't even look at the tower and the turret that was tracking them. I had a terrific time shooting them up, and killed the gunship, MAX and a load of infantry. They finally got me when I ran down the stairs to make sure they weren't hacking my tower, and of course they were waiting for me to do that.
