Looks like Half-Life Opposing Force, Gearbox' upcoming H-L add-on will be debuting at the beginning of next month on both sides of the Atlantic. Randy Pitchford's .plan file has word that Gearbox Art Director Brian Martel "drew the short straw" so he's going to be at the show in London doing demos of Half-Life: Opposing Force "for all the hungry Euro press." Also, word on the Ground Zero Exhibitors page is that "Gearbox Software will be at Ground ZERO, showing the first public demo of Opposing Force." ECTS is September 5-7 in London, and Ground Zero is September 9-12 in in NYC.
