Unique to Free Fire is the EP mechanic, which acts as another gauge to watch aside from HP. In essence, players consume EP slowly when they lose health, acting as a “buffer” for healing HP before players have to use regenerative items. This is a nifty way to save lives in a pinch, but the tricky part here is that players don’t necessarily regenerate EP by default.
Rather, players can only get EP by doing certain tasks such as staying at campfires. Players need to take this into consideration before heading deep into safe zones. Staying with full EP or high EP as much as possible can greatly help players in the event that there aren’t any regenerative items nearby, or if they need to head from one firefight to the next without any breaks.
