the big table's oxygen supply is dwindling. therefore, one necessity for survival is to refill low oxygenated areas and thus avoid asphyxiation. overuse of firearms depletes the oxygen more quickly. in some areas, oxygen can be replenished (an unlimited number of times) by finding yellow oxygen boxes known as "air systems" (as). when the player has a regulator, an as allows him to refill it. if the player is not using the oxygen level indicator, a red emergency light will indicate a low oxygen level. low oxygen level rooms will appear in red on the player's map. oxygen grenades can be used to replenish low oxygen level rooms or hallways.
