Looked cool until I saw it's PVPVE. I think this would be a ton of fun as a single player game. Watching the ladder climbing and time to activate the radio was painful, and I'd hate for that to be a major part of the gameplay loop.
Ladder climbing is important, but most ladders are short ones. You only need to climb the radio tower once every hour or longer. It's only when you extract.
I've played twelve hours of the demo, ten of those last Sunday. Had a lot of fun. Was playing the game with a friend, and we loved the pvp part. The coolest thing about the game is that you can make and design your own trampler, using buildpieces. After we made our first trampler, we went around the servers trampling on everyone. We won a fight 2v3 and another one just after that in a 2v4 situation. Our trampler was designed from the ground up to be run as a two-men team, and it worked like a charm. I was above running guns and engines, and my friend was below piloting and running repairs, in a fully enclosed box of steel.
