1. Life Gauge
Keeping the Life Gauge topped up is therefore vital, but it’s just as important not to panic and keep filling the gauge unnecessarily with precious items. Though you can replenish it with healing objects such as Rations and Noodles, you should take care not to waste them – especially on higher difficulty levels. Using a Ration when Snake’s Life Gauge is 80% full, for example, is plain foolish. You usually don’t need to even think about refilling the gauge until it drops below 25%. During boss fights or difficult skirmishes, you should instead equip Rations, Noodles or Regain and position them as an “active” item. Once Snake’s health reaches zero, these will be automatically used until your stocks are exhausted.
One other method of restoring Snake’s health is simply to find a safe hiding place and let him stand still. After a few seconds the Life Gauge will slowly start to creep back up. If you crouch or go prone, it will refill more quickly. If you have good cover, you’ll find that this even works during boss battles. This can be a great way of refilling your Life Gauge for free – essential when playing on a high difficulty level. Note that recovery speed depends on the condition of Snake’s other main gauge, the Psyche Gauge; the higher the Psyche Gauge, the quicker the Life Gauge refills. (Incidentally, if you have an extended break from playing MGS4 that lasts for more than 24 hours, you may notice that Snake’s Life and Psyche gauges are refilled by 20% per day. It’s hardly necessary, but a nice touch nonetheless.)
