Cell 1, Foofinoo
"We received a call, coming from Black Mesa. Terrorists would have taken scientists as hostages. They would be in the Sector E, the "Biodome Complex"... It's been a while since they want that the experiences carried out there are suspended. Maybe planting abomb would be easier and more efficient... Anyway, you gonna be sent there to save the scientists. But be careful, weird things seems to go on over there..."
