Omnissiah be praised, Warhammer 40,000: Space Marine 2's system requirements are here
In the grim darkness of the far future, there is only War, unless you don't have a 64-bit PC with an Intel Core i5-8600K equivalent and at least eight gigs of RAM, in which case you'll have to, I don't know, live in everlasting peace, or something. I'm pretty sure not having eight gigs of RAM is heretical, but never fear, you can probably compensate by taking a leaf from the God-Emperor's book and arrange for a host of dying psykers to pour their brain energy into your motherboard.
All of which is to say that Focus Home have released the system requirements for huge-shouldered action game Warhammer 40,000: Space Marine 2. Find them proudly emblazoned across the header image above, and written out for easier copy-pasting in the blockquote, below.
