As a member of the FAU-G unit, fearless and united guardsmen participate in border patrol missions. They also attempt to destroy enemies that threaten the peace of their territory. During these missions, they encounter many enemies equipped with various melee weapons. This game features different fighting styles for each fighter. This game rarely includes weapons in close-range melee battles. This is because of the unique aspects that players experience throughout the game. In order to win, the player must carefully regulate their health and blood loss as they face increasingly difficult enemies. This is because the game doesn't feature a single screen; instead, it features many enemies that gradually appear. There will be many stages the player will have to pass through in a game. These are challenging for players as they transition between easy and hard stages. Additionally, players can save their progress at specific checkpoints throughout each stage. Once they finish the stage, they can track their progression on the progress bar located in the right corner of the game screen.

In battle, you constantly attack foes with your fists to eliminate them before they can retaliate. Additionally, avoid blood drops when avoiding blood loss. This is imperative because fast blood loss leads to death. You can confirm that these two empty slots between the control button and fist are functional by examining your hand during the phenomenon. Several enemies use weapons and fists to attack you. Certain enemies even carry weapons that drop when they get hit. If this happens, you can pick up the dropped weapon to fight back. You can only equip two weapons in two designated slots. Otherwise, your weapon arsenal will be limited to one. But don't worry— you don't need to continuously use them. These weapons warn you of how many times you can use them. When you successfully damage an enemy, the warning bar decreases. If the bar is gone, your weapon will disappear. You have two weapon slots and don’t hesitate to use them. Because additional enemies will use weapons in front of you over time. After completing the FAU-G quest Fearless and United Guards, you receive resources that can be used in-game. At the same time, the game provides you with a number of skins and weapons you can choose from. From there, you can acquire ownership of the skins and weapons by finding ways to use them. Some weapons even have unique designs that are currently untapped.

When players first experience FAU-G, it provides them with breathtaking graphics and an inspiring sense of fearless unity. This gives players new challenges in a unique gameplay experience. For passing many game screens, employing correct weaponry is paramount. This singular fact alone makes for an enjoyable time in many game genres.
