Sniper: Ghost Warrior 2 oxygen drains too fast underwater?

In Sniper: Ghost Warrior 2, underwater missions are often stressful due to the rapidly depleting oxygen bar. Players frequently struggle with the need to surface for air, which compromises stealth and leads to detection or mission failure. This mechanic restricts tactical freedom and makes infiltration unnecessarily difficult. The Unlimited Oxygen modifier solves this problem completely. Once enabled, your character enjoys an infinite oxygen supply, removing the anxiety of running out of breath. You can take your time planning routes underwater, finding the perfect sniper nest, or waiting for patrol gaps without surfacing. This eliminates the pressure of survival mechanics, allowing you to focus on precision shooting and strategic positioning. Whether crossing large bodies of water or executing complex underwater infiltrations, Unlimited Oxygen empowers you to play like a true ghost warrior. Experience smoother gameplay, complete high-difficulty challenges with ease, and enjoy the game without arbitrary limitations holding you back from total domination.
