- "In desperation, world leaders turned to their last chance: an ancient artifact called the 'Time-Lock'. They believed this relic from a long forgotten race was a portal to a point in ancient history, and their only chance for survival. If only they knew how to turn it on."
- ―Serious Sam 3: BFE opening narrative[src]
The Time-Lock is a mysterious device capable of sending someone back or forwards in time, more specifically to the date it was armed. It plays an important role in many Serious Sam titles, and serves as the player's main objective in the Serious Sam 3: BFE campaign.
Overview[]
The Time-Lock is essentially a time machine. In Serious Sam 3: BFE, it requires an immense amount of power, as there are two generators dedicated to powering it, with one in Karnak and another one in Luxor.[1] This isn't the case in other games the Time-Lock appears in. Thus, it is uncertain if other Time-Locks require a power source or are sustained by an independent power source.
For the other time portals that appear in Serious Sam: The Second Encounter, they require a certain item to be activated. In the case of the Mayan time portal located in Teotihuacan, a crystal skull from the city of Palenque was needed.[2]
Given the Time-Lock's mysterious origins and how it functions, the device can cause anomalous effects when it is used. This is seen when Sam arrives in ancient Egypt via the Time-Lock, and a violent thunderstorm erupts shortly after.[3] The effects of the Time-Lock are powerful enough to be felt through space itself, as Mental was alerted to its use after Sam uses it in both The First Encounter and The Second Encounter. As a result, Mental sends his troops to invade Earth and to thwart Sam's efforts in his goal to save the human race, no matter what time period he appears in.
Design[]
The Time-Lock's design varies between its appearances. In Serious Sam: The First Encounter, it is a small gray device made from some sort of metal that can only transport a single person at a time. It can accept organic and inorganic matter, but it will usually strip off any large inorganic objects on someone when they use it, such as weapons.[4] In The Second Encounter, the Time-Lock is much different compared to The First Encounter, appearing as a flat, square-shaped platform that emits glowing particles once it is activated.
In Serious Sam 3: BFE, the Time-Lock has received a complete overhaul, and is now a massive machine that can safely fit multiple people in it and is located just outside the Mortuary temple of Hatshepsut. In addition, it is colored gold and dark blue and the four towers surrounding the Time-Lock are designed like Egyptian human shapes with alien faces on them.
History[]

The Time-Lock being excavated in Serious Sam 3: BFE.
The device was created by an unknown alien race (most likely the Ellians), but discovered by the Sirians during their interstellar travels. During Mental's siege on the Sirians' homeworld, Sirius, they sent the Time-Lock to Earth, a planet they were just starting to explore, to prevent it from falling into Mental's hands. After the fall of Sirius, the last remaining Sirians decided to arm the Time-Lock to their time in case it was needed by the humans for whatever reason. After that, the machine was powered down and the Sirians hid their artifacts inside various Egyptian temples and tombs, leaving behind clues and riddles that they hope humans would understand one day in the future, when the Sirians felt humanity was advanced enough to know how to operate the Time-Lock and the rest of their technology properly. After the remaining Sirians died out, the Time-Lock was buried in the temple of Hatshepsut and was lost for thousands of years.[3][5]
While the Sirians were thought to be extinct, a few survivors placed time portals with each great human civilization on Earth, such as the Mayans and Babylonians. This was part of a backup plan to send someone forward in time to the appropriate era in which the backup spaceship was located, in case anything was to happen to the SSS Centerprice.[6]
A few millennia later, in the year 2063, the Time-Lock was discovered in an excavation site near the temple of Hatshepsut. Once uncovered, the humans began to find a way to turn it on. The implications of this discovery leads humankind to better understanding of alien technology, and eventually they became advanced enough to develop interstellar travel. Thanks to these advancements, humanity begins establishing off-world colonies in other star systems.[3] Several decades later, Mental was accidentally woken from dormancy, and chose to invade Earth.
The humans fought bravely, but ultimately they were no match for Mental's army and their massive numbers. In just 3 years, humanity was staring into the face of its own annihilation. Running out of options, world leaders began making a last-ditch plan to use the Time-Lock and send someone back in time to kill Mental in the past, thus changing the future and sparing humanity from extinction.[3][5] However, the main problem was that, since humans struggled to understand how to use Sirian technology, let alone know the locations of the power generators, they couldn't find a means to switch the Time-Lock on.
In order to look into this problem and find a solution, the Earth Defense Force selected their best scientists and had them dig up some clues from the history of ancient Egypt to better understand what they were dealing with.[5]
Appearances[]
Serious Sam: The First Encounter[]

Sam arrives in ancient Egypt via the Time-Lock.
Sam is seen arriving via the Time-Lock after the events of Serious Sam 3: BFE. He appears to hover in the air for a few seconds, then is abruptly dropped to the ground. The power of the Time-Lock being used is powerful enough to be felt through space, and this has alerted Mental, which causes him to send his troops to Earth in an attempt to stop Sam. The effects of the Time-Lock have also caused some atmospheric disturbance, but the weather calms down after a few minutes.[7] Now that Sam is in the right era he needed to get to, he has no further use for the Time-Lock and proceeds on foot to start his journey.
Serious Sam: The Second Encounter[]
The Time-Lock plays a large role in The Second Encounter, with several of them existing throughout different time periods. It seems that the Sirians bought these time portals to Earth so that someone from the future could activate the backup spaceship, in case anything happened to the SSS Centerprice, a spacecraft that would be sent to Earth if a homing beacon was activated in Egypt.[8]
Sam activates this beacon and the ship is sent to Earth. Once he makes his way to the Great Pyramid, Sam manages to board it after a massive battle between Sam, Mental's forces, and Ugh-Zan III. Unfortunately for Sam, something collides with the ship and it ends up crashing in Sierra de Chiapas. After the crash, NETRICSA downloads a large quantity of data from the wreckage of the ship and tells him about a backup spaceship that he can use to get to Sirius, though it requires the Holy Grail and its powers to be activated.[8] NETRICSA also informs Sam about the time portals that were placed with each great human civilization. To activate these portals, a special item was required.
In order to get to the Time-Lock that was left with the Mayans, Sam travels on foot through the city of Palenque and obtains a crystal skull; the item required to activate the time portal that will take him to the ancient Persian era.[9] Next, Sam heads to Teotihuacan and eventually ends up at the Sun Pyramid where the Mayan time portal is located.[10]
However, little does Sam know, is that Kukulkán, The Wind God, is guarding the portal.[11] After Kukulkán is defeated at the hands of Sam, he sees Stone as a worthy opponent and opens the time portal for him, sending him forwards in time to ancient Babylon. In Persepolis, Sam arrives at a ziggurat, and NETRICSA tells him that the Babylonians left a time portal nestled deep in the city, but getting there will be a long and tedious journey.[12] Sam continues on his quest, fighting more hordes of Mental's forces through Persepolis, and eventually makes his way to the Tower of Babel.[13][14]
Upon arrival, Sam fights through many courtyards before being able to enter it, but it is not long before he is greeted by the Exotech Larva, a large insect-like cyborg that Mental created to prevent Sam from entering the second time portal.[15] After a tough fight, Sam defeats the beast and enters the last portal, which sends him further in time to the medieval era, in 1138 AD.[16]
Serious Sam: Next Encounter[]
In Next Encounter, Mental warns the Evil Serious Sam Clone not to use his personal Time-Lock. However, the clone ignores his advice and hops into it, which starts the problems in the game that Sam himself has to fix.
Serious Sam Advance[]
Humanity has managed to adjust the Time-Lock so that they can warp anywhere in history. They use the Time-Lock both to explore the past and to make sure that Mental doesn't tamper with the past in any way. The game starts out with some agents from Earth disappearing during a routine time traveling trip. Sam is sent back into the past via the Time-Lock to investigate what happened.
Serious Sam 3: BFE[]
The Time-Lock plays a much larger role in Serious Sam 3 than in other any game thus far. At the start of the game, Professor Stein and his escort, Bravo Team, manage to find some clues on how to power-up the Time-Lock within the Egyptian Museum in war-torn Cairo. Eventually, though, Bravo Team lose contact with HQ and are killed, leaving the professor on his own.[17] Alpha Team are sent out to rescue the professor and to bring him back to headquarters. Sam, the only surviving member of Alpha Team, decides to rescue the professor alone, but he is too late when he discovers Stein's remains after he is killed by the aliens.[18] However, Sam manages to upload Professor Stein's data from his cell phone back to HQ, then he leaves Cairo to get to the Great Pyramid.[19]
Sam travels to the Great Sphinx, which apparently leads to a clue. The recovered data deciphered from Stein's cell phone indicates that there is something underneath the Sphinx and, presumably, a way into the secret chamber inside the Great Pyramid. Sam, however, takes the easy way in and blows the Sphinx up, which reveals the entrance to underneath the pyramid.[20] Inside, Sam finds a Sirian chamber and a hologram that reveals the location of the Time-Lock's two plasma generators. After he sends this information to HQ, Hellfire arrives to extract him via helicopter and takes him to the first generator's location in Karnak.
Once Hellfire drops Sam off in Karnak, he activates the first generator, Horus. He updates Quinn and tells her that the first generator is online. She is excited to hear that they finally have a piece of Sirian technology running, as they have never been able to achieve this before in the past.[21] After that, Sam travels to Luxor and activates the second generator, Anubis. With both generators operational, Quinn cheerfully tells Sam that he is relieved of duty and Charlie Team is ready for insertion to extract him and take him to the Time-Lock.[22]
However, later on, the Earth Defense Force come under attack by an ambush after Mental's forces attack the base. This results in the death of the majority of EDF personnel, including Hellfire and Quinn.[23] with Charlie Team missing as well, Sam vows to get revenge on Mental and decides to head to the Time-Lock on his own. He finds a car, fills it up with gas, and drives all the way to the Mortuary temple of Hatshepsut, the location of the Time-Lock.
From there, Sam fights his way to the temple of Hatshepsut. As he reaches the final stretch, he is attacked by Ugh-Zan IV. Thanks to some creative thinking, he manages to kill Ugh-Zan IV and enter the Time-Lock. Sam is then warped to ancient Egypt, and begin his journey to defeat Mental.[24]
This version of the Time-Lock is ultimately destroyed after the Moon plummets into Earth's atmosphere, but it still exists in The First Encounter, The Second Encounter and Serious Sam: Siberian Mayhem timelines.
Jewel of the Nile[]
During Sam's return to base, Quinn informs him that the Time-Lock failed to come online as they had expected. Both of the generators were turned on, but it hadn't started the Time-Lock because, apparantly, there is some kind of fail-safe mechanism which has to be activated in order to power on the Time-Lock. Quinn in unsure exactly where this control room is, but she believes it's located on the island of Philae. With these new orders, Wilson changes course to drop Sam in Philae to find it. Sam fights his way through the enemy forces on the island and enters a Sirian chamber which he believes is the Time-Lock controll room, but instead is just an empty chamber with nothing but a key and an XL2 Lasergun.[25]
Quinn tells Sam that, as the control room is not there, it must be located in Abu Simbel, which had seen a lot of Sirian activity in the past.[26] As all the EDF's helicopters are needed elsewhere, Sam has to take a boat to get to the town. He digs through some clues left behind by the ancient Egyptians and is successful in solving in finding the statue of Nefertari, the key to opening the door inside the temple of Rameses. Sam enters the room, only to find another key similar to the one he found on Philae.[27] He tells Quinn about the bad outcome, and she believes the last possible location could be inside the Tomb of Sethirkopshef, which is about 3 miles from Abu Simbel. Sam does as instructed, goes to the tomb, and powers up the Time-Lock inside the control room.[28] With the Time-Lock fully operational, Sam heads back outside, but not long before Mental sends in a massive Scrapjack to stop him. Sam kills Raahloom, and Wilson arrives to extract Sam back to headquarters.

Trivia[]
- In Serious Sam 3, Sam says he will see Mental in 3000 BC, but ends up in 1378 BC instead.[24] He probably just wasn't aware of the exact date the Time-Lock would send someone once they entered it.
