THQ released the final part of the E3 demo gameplay today and it continues to show off the high adrenaline action that the first two pats gave you. For those of you who have not been keeping up to date with the videos, Khan and Artyom decided it would be a good idea to slip through a slew of enemies and try to remain undetected, but things got a bit out of hand and now they are in a desperate struggle for survival against a ton of angry enemies. The end of the trailer also promises a full length 12 min trailer on August 23, but until the check out part 3 of this epic demo.
