I spent 21 days planning, modelling and texturing all the weapon components needed for a FPS game project at The Game Assembly - a loot-filled treasure hunt within the hulk of a crashed spaceship, inspired by Destiny.
Towards the end of the project, my programmer colleague crunched the numbers and we stared at the sum of guns for a good long while :)
