Following the prompts on the screen, Chen Sha quickly shook his mouse and clicked the left button to perform an escape action.

The protagonist, while letting out painful cries, struggled desperately to break free, kicking the zombie aside and crushing its head with his foot!

Of course, the camera shifted slightly at the crucial moment to prevent overly graphic scenes.

Although the ESRO itself was a rating organization, Bao Xu and Huang Sibo didn’t want “Sea Fortress” to be classified as a game unsuitable for teenagers, as that would reduce the player base.

For similar scenes, they made some simple adjustments to avoid making them too explicit.

The protagonist fell to the ground in pain. From the first-person perspective, one could see a bloody wound on his right leg where the zombie had bitten him, creating a hole in his camouflage pants, revealing a bloody mess underneath.

The protagonist struggled to get up again and moved with difficulty toward the exit.

Finally, he arrived at the last door.

The door was slightly ajar, with a faint light visible through the crack, and some slight sounds could be heard.

The protagonist pushed the door with both hands.

But the moment the door opened, a blood-covered zombie suddenly lunged from behind it, knocking the protagonist to the ground!

“Crap, crap, crap, crap, crap, crap…!”

Chen Sha was badly frightened. The zombie’s face was very close, directly occupying the entire screen, with blood and rotting flesh visible on its teeth!

Although the zombie’s face wasn’t made to be especially realistic or detailed, the sudden appearance of the zombie was completely unexpected for Chen Sha, scaring him badly!

This was a zombie in a mercenary uniform, with an intact body and robust muscles, unlike the previous zombie, which was incomplete and weak.

This mercenary zombie directly knocked down the already injured protagonist, desperately stretching its head toward the protagonist, making “heh heh” snarling sounds while trying to bite through the protagonist’s neck!

The protagonist’s right hand tightly gripped the mercenary zombie’s throat, while his left hand reached toward the zombie’s waist.

“Bang!”

A gunshot rang out, and in the blood-blurred vision, the mercenary zombie was pushed away by the protagonist, its body falling to the side.

There was a handgun at the mercenary zombie’s waist. The protagonist drew it out and shot the zombie in the head!

The screen simulated the effect of vision gradually blurring due to significant blood loss, so Chen Sha didn’t see the details of the zombie’s head being blown off, but this blurred vision combined with the protagonist’s voice actually highlighted the tense atmosphere even more!

Chen Sha was badly frightened.

What a setup!

He was told it was an FPS game, but it ended up being like a horror game, scaring people to death!

These two battles were just cutscenes; as long as you had hands, wiggling the mouse would get you through, but Chen Sha still broke out in a cold sweat.

Mainly because both the first zombie biting the thigh and the second door-ambushing zombie appeared when he had absolutely no mental preparation, so the shock effect was particularly obvious!

Next came a section of standard tutorial mode.

The system began to introduce how to aim, shoot, reload with the handgun, as well as standard operations such as crouching.

The operation mode was basically no different from other FPS games, and Chen Sha quickly got the hang of it.

In terms of the story, the protagonist found a medical kit in the cabinet of this room and wrapped bandages around the wounds on his abdomen and right leg.

At the same time, he also found an access card on one of the corpses in the room.

After giving himself simple treatment and bandaging, the story mode of the game formally began.

At first, he encountered some weaker zombies that didn’t move very fast, and headshots generally took them out with one bullet.

But the protagonist had very few bullets initially, and zombies always suddenly appeared in some unexpected places; one moment of inattention and you would be bitten or knocked down.

Chen Sha’s shooting skills were good, but he was still quite frightened.

The game didn’t directly or bluntly tell the player the protagonist’s identity and purpose, but as the early plot progressed, Chen Sha also had reasonable guesses.

The protagonist was clearly inside some secret base where a mysterious virus had broken out for unknown reasons, and large numbers of humans had been infected and turned into zombies.

The protagonist was not only being hunted by the mercenaries of the secret base but had also been bitten by zombies.

Although the protagonist had used bandages from the first aid kit to bandage his wounds and stop the bleeding, the virus would eventually take effect, and the protagonist turning into a zombie was just a matter of time.

There were no friends or companions here, nor any equipment to contact the outside world. The protagonist could only search for supplies alone in the dangerous base, deal with zombies and some living human mercenaries, and do everything possible to survive.

In this process, players would face various challenges.

In terms of combat, facing zombies and mercenaries required completely different combat approaches.

Zombies had acute hearing; rashly firing a gun might cause nearby zombies to swarm in. Unless the player had extremely precise shooting skills, they would likely be overwhelmed when surrounded.

Moreover, even after killing zombies, players often couldn’t replenish their bullets and would quickly find themselves out of ammunition.

So, the best way to deal with zombies was to use melee weapons and assassinate them stealthily one by one.

Mercenaries, on the other hand, often patrolled in groups of three to five. If one person went missing, the others would immediately become alert, loudly warning their companions and all going on high alert.

Therefore, assassination wasn’t a good approach for dealing with mercenaries. Players needed to engage in gunfights with these mercenaries as much as possible and finish them quickly. After all, killing mercenaries would allow players to replenish bullets, and sometimes even acquire new firearms.

Of course, in some situations, players would simultaneously encounter mercenaries and zombies, and they could completely lure zombies and mercenaries to fight each other, then step in at the end to reap the benefits.

On some levels, players could enjoy special items, such as using a heavy machine gun to mow down zombie hordes at specific locations. But most of the time, players had to carefully plan their use of weapons and bullets, cautiously seeking survival, with every bullet being extremely crucial.

Although the scenes in the game were all repetitive base interiors, the layout still had a maze-like feel.

Some doors were blocked and impassable, some required access cards, while others could be destroyed with special items…

As players continuously progressed, enemies became stronger and more varied.

Worse still, the protagonist’s mental state deteriorated, specifically manifested as: the screen momentarily blurring, then returning to normal; the protagonist’s hand shaking, causing the crosshair to automatically drift; walking slowly, or being unable to walk in a straight line…

Finally, Chen Sha encountered the first mini-boss battle.

The first mini-boss was a powerful mutated zombie, which, compared to other zombies, had the advantage of being very large with greatly increased health.

However, this was after all only the first mini-boss. With the various weapons accumulated earlier, Chen Sha successfully defeated it.

Afterward, the protagonist collapsed to the ground exhausted, his vision gradually blurring.

He was severely depleted of energy, and the infected virus was eroding his consciousness.

In the end, the protagonist closed his eyes, and the screen went black.
