Where do you all come from?
We spend 99% of our time working to make Natural Selection 2 awesome, so we do not often think about 'corporate' stuff. We do however have an Unknown Worlds motto: 'Unite the world through play.'

Our office is a prime example. The majority may be US citizens, but we also have an Austrian, a Pole, and an Australian here in San Francisco. Offsite, Indonesia, France, the UK, and many more countries are all represented by full-time off-site developers. Our volunteer playtest group is a rainbow of nationalities, with a plurality of accents calling out 'kill that Onos!'
