War Assets represent the military strength Shepard has gathered to fight the Reapers. These are acquired by completing main missions, side quests, scanning planets, and making certain dialogue choices. Galactic Readiness, influenced by multiplayer or the N7 HQ app, multiplies your War Asset score. A higher effective military strength unlocks more favorable endings. Prioritize gathering as many War Assets as possible.

Types of War Assets:
- Military Forces: Fleets, ground troops, special forces.
- Technology: Weapon upgrades, ship enhancements.
- Personnel: Scientists, engineers, intelligence agents.
- Strategic Resources: Fuel, raw materials.
