Lazarus Labs

Lazarus Labs is the ninth level of the new Doom reboot, with the mission involving the map called simply "Lazarus."

Penetrating into the heart of the initial demonic invasion of Mars, your mission is simple: find the Argent Accumulator so that you can get back to Hell and reclaim the Crucible. Hell's strongest minions on Mars will be standing between you and the way back into Hell, but they're nothing you should not be able to handle.

There are nine secrets, four Elite Guards, one Field Drone, one Argent Cell, and two Rune Trials located in this level. The Cyberdemon is encountered at the end of the level as a boss monster, and must be defeated twice to continue.

Lazarus Labs
''The Lazarus Labs is a sub-division of the Advanced Research Complex, and is also accessible at the highest clearance levels. Located deep underground to prevent infiltration (or exfiltration), the Lazarus Labs are home to the longest-serving and most dedicated UAC staff. Information regarding the Lazarus Project is hard to come by as its members are highly secretive and well disciplined. What is known is that any cross-dimensional anomalies, entities, or artifacts are immediately sent to the Lazarus Labs for research, and are never seen again. However, promotion to the Lazarus Project is seen as a badge of honor among the UAC staff - despite not knowing exactly what their work will entail.''

An Important Message
''Fellow disciple, this message has been sent to you in recognition of your service to the Lazarus Project. I am Olivia Pierce. You have been granted the highest level of clearance we allow in the Lazarus Project, and as such you are expected to partake in all rituals, sacrifices and vivisection programs (both demon and human) as requested - whether as a practitioner of the dark arts or a patient of a cleansing. As we work tirelessly to open the gates to Hell, remember our mantra: "The science will cleanse us".''

''Our recent expedition to the Great Steppe resulted in the retrieval of new tablets which will help us further decode the Helix Stone. I must again reiterate the importance of fully decoding this stone. The scriptures tell us that it holds the key to both realizing our future and destroying us - so we must know it before the enemy. The enemy will come and we must be ready. While we are decoding the latest artifacts and relics, there will be no rest, no leave and no sleep. We must succeed. Our lives mean nothing. Opening the gates is everything.''

Trivia

 * This level is split into two parts, possibly to put less stress on the hardware of console versions.
 * If using the Saving Throw rune, if it's already been activated, the rune will reset after the cutscene that triggers with the Helix Stone.
 * It should become quite apparent to the player how to use his runes. For example, some runes such as Armored Offensive are more useful in battles with many different enemies, whereas Saving Throw is more useful in boss fights, such as against the Cyberdemon.
 * The player gets several warnings of his impending encounter with the Cyberdemon. In one place, he hears an ominous thumping off in the distance; shortly thereafter he finds a Data Log that depicts it (usually he only obtains one for a specific demon after killing the monster in question, and not from a pickup); and finally there is the empty cell where the Cyberdemon was kept where he finds the Automap.
 * One recording finally identifies the whispering contrabass voice that narrates the Doom Slayer's testaments and announces "He's here!" at the beginning of Kadingir Sanctum: a lord of Hell that Olivia Pierce has been collaborating with.
