Gunrunner

Someone has a gameplay video up at :-

I think he runs a bit much considering how nasty and quick some of the formations can be, if you have been running for a few seconds and
sense they're gonna come on perhaps behind you it pays to hold your ground
before jumping over a few objects :)

Also, don't duck until you see you have to, if you duck too much and something
comes behind you it takes longer to turn around and it'll be too late.

Great game, absolutely rock solid but great :)
