SAS: Zombie Assault 4
The SAS operatives begins with defending a shuttle while the pilot fixes the ramp doors. After about five minutes, the team faces a mutated zombie(s). As soon the zombie is dispatched, the team leaves Kurios station.

Meanwhile, as the team is gearing up for their next mission, an intel officer order the men to collect a vaccine found on Thera by Combot, their AI regarding the defense of the Federation. However, the president address to the public is also a signal for a Jolt Ship to launch their nuclear missile to destroy Thera. As a result, the teams mission window is less than 15 minutes to retrieve the vaccine and evacuate. The team still manages to collect the vaccine and evacuate.

Later on Aartis, Combot receives transmission of a SOS coming from a heavily populated city. The team is then sent to the city and eradicate all zombies on site. Also, if any civilian are infected, they are to be shot on site. After rescuing the civilians, the team are ambushed by a mob of zombies.

The SAS are then informed that Combot has been compromised. With that said, the team are sent to a market where they encounter purge nests. Also, while on the mission, one of the operative says how there's still twinkies. Soon after destroying the nest, the team encounters five pods in the parking lot. Regardless of whether the team destroy all the minion pod, remaining pods suddenly explode and releases all the zombies found inside.

Soon after, the team is then sent to a mansion where a VIP is located. The team objective is to retrieve the VIP and evacuate the area alive. The team enters the mansion and kills any zombies found inside. When the team finds the VIP, the operatives seemingly starts to regret rescuing the VIP. When a operative acquires any loot with the VIP with them, the VIP will say that the loot belong to him, resulting in the operative ready to shoot the man down. While fighting the zombies, the VIP notes that his robotic servant are acting weird.

After evacuating the VIP, the team are sent to an underground building, with the doctor informing the team that their hospital is defended by advance weapons not connected to Combot, who makes his presence known by activating weapons. While activating the power to the hospital, the team founds 3 dead SAS operative. Whether these men were killed by Combot or died by the infection is not known.

Although power is back online, Aartis is nearly over run by the zombies, the team has to evacuate the planet. However, there is a horde of zombies are surrounding the area is moving in to fast even to set up barriers, leaving the team to defend with their lives. Needless to say, the team survive and evacuated the planet.
