Valve has released Parts four and five of the Portal E3 Demo in HD.
The 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”, says Valve. “The good news is they’re even more hazardous to the health of turrets”.
Good to know.
Parts two & three were posted earlier today. Parts six and seven will be released tomorrow.
Portal 2 releases in 2011 for PC, 360, Mac and PS3.
