Arrowhead have any number of crossover collaborations in mind for Helldivers 2.
eeeeewwwwwww
For a time, they envisaged a system that would effectively let individual Helldivers hallucinate licensed worlds, with map cosmetics that are invisible to their non-buyer comrades.
That would be the least worst way to implement, but I assume for a time means they won’t do the invisible to non-buyer citizens part. While killzone looks like it will fit the aesthetic, anything that doesn’t will instantly ruin helldivers for me because the theme is half the fun.
Super earth crushes individualism in its helldivers. You are a defrosted soldier and you will do your duty. What you wear only matters in how long you last before the next defrosted soldier gets thrown into the meat grinder.
