my friend helped make the HL engine and halflife all together so he's helping make the game. more ppl know about this game than you think.. but i got a demo thanx to him so i know the true power of killing swat with a sword!
^I may have met your friend because on Valentines day I got to tour Valve and play test Goldrush for TF2. I met the creator of DOD, CS, and some of the Portal team although sadly Gabe was off that day :(
Also ask your friend if they liked the pinata of Gordon I gave to them?
