Jesse's health regenerates slowly, but you'll primarily rely on picking up blue health shards dropped by defeated Hiss. Energy is used for all supernatural abilities (Launch, Shield, Evade, etc.) and regenerates quickly. The Service Weapon has infinite ammo, but each form has a cooldown period after sustained fire. Managing these three resources effectively in combat is paramount. Prioritize health pickups, use energy abilities strategically, and switch Service Weapon forms to avoid cooldowns.
