Okay, if you donít want to sit through the whole explanation (which we recommend because itís actually pretty damn cool) the actual gameplay starts at 1:55 in. And if you skipped the whole thingÖ then youíre a jerk. What? The videos we find arenít good enough for you? Fine, thatís fine, weíll explain it. Waterloo labs shows us all how to play Half-Life (well, a flash version of it) using some Accelerometers, a big olí board, a bit of programming skill and some guns. Alright, despite being completely pointless because you could just as easily use a light gun for this sort of thing, itís completely fucking awesome. Thinking about it though, imagine the possibilities of this! We could use this as training device for the military! Or even just put it in arcades! Who said that playing video games are just murder training simulators?!
