If you’re looking for a bargain this weekend then look no further than Valve’s digital distribution platform Steam. The ‘multiple award winning’ World of Goo is now available for the low low price of £4.24 for this weekend only. After this weekend’s promotion the price will go back up to £16.99, so get it while it lasts.

If you’re not convinced enough to slap down what’s basically pocket money then you can also download the demo through Steam to give it a try. If you’ve got any sense then that should have you reaching for your credit card in no time at all. You’ll also be helping an independent developer.

If you’d rather not play it on the PC then the game is also available on Wiiware, where you can use your remote to build structures and solve puzzles using balls of goo.

Steam always has some rather good promotions on, and this weekend is no exception. If you’ve never bought a game through digital distribution then this is your chance to try it out, and I assure you that you won’t be disappointed.
