Solution
This was quite a challenging task for a few reasons. First and foremost, the deadline was really tight. Also our team had access to somewhat limited project information. Additionally, we had to do the majority of development using remote hardware which affected teamwork to some extent.
In order to create numerous 3D assets and maps, we had to to quickly scale-up our art department by hiring around 100 modellers. Of course it was not an easy task to select and onboard such a large number of people. Needles to say, they all had to get on the same page with the key crew ASAP. Seasoned Art Leads were the right answer to this challenge.
Level design was another time consuming piece of work. Although we had very clear directions for each map, their average size of several square mile was impressive. On the other hand, working on realistic guns was a real pleasure!
