As we've come to expect a new game has been added to the latest Humble Bundle on Steam, this time with SpaceChem joining Frozen Synapse. If you're not familiar with SpaceChem then shame on you, but go read Allen Park's review of it from earlier this year to see why you should be excited!

Keep your eyes peeled for further updates, as this bundle still has six days remaining. Remember that if you beat the average price of $4.75 and you get five additional games, a prize well worth the price of admission. What are you waiting for, just buy it already!
