Can you imagine XCOM 2 as a romance sim? Well, maybe this isn't quite that, but a mod called Squad Cohesion brings elements of Fire Emblem into the world of XCOM 2.
While the mod doesn't bring any Fire Emblem aesthetics to XCOM, what it does instead is introduce relationship building statistics for your squad members. Creator RealityMachinima explains that "this mod puts a dash of Fire Emblem into your XCOM" and it will give "small buffs for squads that trust in each other." Basically, you can play matchmaker or grow friendships in your unit, which sounds downright amazing.
Certain actions will increase these relationship stats, such as healing a squad member or carrying them out of battle. While these relationships continue to grow, you'll receive notifications about increased stats. Relationship perks include stat gains towards skills such as aiming, critical hits, hacking, and will. But be careful, because these relationships can crumble, too. If a soldier falls in battle, and another squad member was close to them, the surviving friend might receive the "Shaken" status, which lowers the entire unit's willpower. The closer these two squad members were, the higher the chances are of this occurring.
