I admit, I never got around to playing any more of Human Head’s shooter than the demo. However, I return from London Town to see that if I had any spare time, now would be a good chance to change that. For this weekend – and this weekend only! – it’s on sale on Steam, for a mere $4.95. And for Europeans, that means it’s at least seven ultracheaps. It divided critical opinion upon release - I know Jim was a big fan of the physics-warping levels, but it was critiqued even more than Bioshock for its repawning system. Those who’ve played it: Worth five dollars? Seriously, how could it not be.
