Pre-ordered and pre-paid.
I want the full Sandbox2 editor as much as the game.
I was initially disappointed in the demo, because I played it like any normal shooter, it was pretty, but not anything revolutionary.
I re-played using stealth, then strength and speed and started taking advantage of the destructible environment and physics.
"Oh, THAT's what they were talking about."
Once you start thinking outside the regular FPS mindset, it gets SO much better.
