As promised last week, Sierra has released the first of several levels to be released for the Half-Life Opposing Force mission pack made by GearBox today. You can grab the level here. Sierra hasnt given official word on the release but a half dozen people have emailed me saying its legit. Keep an eye on the official website for more details probably today. Thanks JayZee and many others for the tip. 5:20 update: Looks like Frans with his sharp FTP skills spotted the second HL: OppFor level already posted on the FTP now.
