Portal E3 Demo: Parts 4 & 5 Out Now
Valve today released Parts 4 and 5 of the Portal E3 Demo in HD. These clips show off two new gameplay tools: Pneumatic Diversity Vents and the Thermal Discouragement Beams. The bad news is these new puzzle elements can be hazardous to your health. The good news is they're even more hazardous to the health of turrets.
Parts 6 & 7 will be released tomorrow. For more information, please visit www.thinkwithportals.com
