Man.
What a buggy demo.
And what a crappy port, keyboard bindings wise.

After about 15 minutes of play, stuff started working hap-hazzardly.
Sometimes parachute would no longer work, or fire wouldnt work, or jump would not release you from the grapple. I think the zoom got weird at one point (wouldnt un-zoom).

As for binds, seriously, What the duece? Seperate forward/reverse/left/right/EVERYTHING from when walking? That is just stupid. Very stupid.
My mouse button 5 remapped to the Ctrl key. HUH?

Wasnt very fun for me. Uninstalled after 20 minutes into it.
