After Half life 2: Episode 3

I would hope Half Life 3 would be announced, being worked on the same crew as all the time... Pray for no Codecs being stolen :P... But Half life 3 would be great, Since for me It's the Series of our Generation.

Fyi, Go Soviet Motherland!

This is Level 2 in ROBOT HELL!!!

See you there :P
