Good Old Games just put up their 100th game and they are giving it away for free. The game is a point and click adventure named Teenagent. Here is their description
"In the middle of a beautiful summer day a teenager is captured by two men in dark glasses and long coats. This is going to be a very interesting day!
It's been six months since the super secret secret service agency - RGB - started investigating the mystery of the gold missing from the main European bank, to no avail. They are so desperate that they went to a fortune teller for advice and she told them to make you into an agent.
You are Mark Hopper, the average teenager, who becomes an RGB agent and the agency's salvation.
Your rewards will be girls, because every girl loves the secret agent, don't they?"
