The level of detail in Helldivers 2 is insane for the type of game and company size.

Deformable terrain and buildings, enemy animations when you shoot off different limbs and they keep moving towards you, your cape burns off more and more as you use your jetpack, etc.

Call of Duty has 3,000 devs working on their titles.

Arrowhead has around 100 employees total.

I very much believe this game took that long with a team that size, and it shows and is a large part of why it’s been so successful.
