The XCOM Memorial Wall on Facebook hosts all of the fallen soldiers added by mournful players. Add yours by simply clicking that big button on the top and filling out the appropriate assets. Turns out Facebook can be used for some pretty cool (and heart-wrenching) things, after all.
The XCOM: Enemy Unknown team has created a way to honor your fallen soldiers! The XCOM: Enemy Unknown Facebook Memorial Wall allows users to share the names and details of their fallen operatives along with a brief eulogy to memorialize the members of their squad who died protecting Earth against the alien invaders. They may be gone, but they will not be forgotten.

Good luck, Commander. We will be watching.
