Part 4

Learn about checkpoints, the Dossier map, and rune upgrades in Doom (2016). Checkpoints preserve demon kills and pickups.

Checkpoints:

• Things preserved by checkpoints: demon kills, pickups (except those dropped by demons), Health, Armor, and Ammo levels.
• Things lost by dying after a checkpoint: the fill-up delivered by Argent Cells, and partial (pending) powerups at the time of the checkpoint.

Your Dossier:

The Dossier is accessed by the central button on PS4. In-game tutorials explain its features well.

• An Auto-Map enhances the map in your Dossier. Praetor Suit upgrades can improve the map.
• Weapons and Praetor Suit Upgrades are explained over the first few Missions.
• Tutorial Codex pages are automatically added to the Codex page, which lets you see if you have missed any Codex Entries.

Navigation:

The Dossier has a 3-D map that lacks a coordinate system, labels, or a reference direction. It does provide icons that can be used as landmarks. Pay attention to the names of major rooms/locations, as you will likely visit them multiple times.

Difficulty Levels:

Difficulty levels affect the damage done by demons, gains from ammo, armor, and health pickups, and the 'Rich Get Richer' rune. They do not affect the number or placement of demons, the chainsaw, secrets (except the size of an Armor pickup), or the 'In-Flight Mobility' rune. It is uncertain if monster health, user weapon damage, environmental damage to the user, or environmental damage to demons are affected. Ultra-Nightmare is the same as Nightmare for these effects.

Runes:

Hints are provided for completing Rune Challenges and upgrading runes.

• Vacuum: Easy to get and important. Upgrade is easy. Remember to equip it after completing the challenge, as it won't remind you in Nightmare mode.
• Dazed and Confused: Useful for the Bosses at the end of Mission 11 and for the 'To Be Knighted' Combat Challenge for Mission 4. Without Jump Boots, Glory Kills on Hell Knights can require setup.
• Ammo Boost: Very useful and recommended to be on much of the time.
• Equipment Power: Makes grenades powerful and is trivial to upgrade by throwing 30 grenades with the rune enabled. Upgrading with Praetor Tokens makes grenade throwing faster, easing the upgrade.
• Seek and Destroy: Useful for most berserk powerups, which are good times for upgrades.
• Savagery: Useful for most berserk powerups.
• In-Flight Mobility: Almost vital for the last boss fight, and its upgrade is critical. It may make sense to work on this upgrade alongside 'Dazed and Confused'. Challenge tips: single jump across the split is required; double-jumping wastes time. There are two chances to hit the mid-air relic. Upgrade requires 25 Mid-Air kills (referring to you). Glory-kills from above are the easiest way to get this upgrade, making it sensible to combine with 'Dazed and Confused'.
• Armored Offensive: Very useful and easy to upgrade by keeping it on a lot. The upgrade is measured by armor points picked up; a Mega-Health contributes 200 points.
• Blood-Fueled: Useful during Berserk Powerups, which are also good times to get the upgrade.
• Intimacy is Best: Helpful for the 'Atop the Mountain' challenge in Mission 10. Upgrade hint: best to upgrade by finding a group of The Possesseds and staggering them with the pistol, taking about a minute.
• Rich Get Richer: Quite useful in several Argent D'Nur fights. Upgrade requires 12 Armor Fillups (Argent Cell and Mega-Healths count). Using Toxic-Sludge for a single point of damage is an option, with an easy access fight in Mission 10, Pounding Rock Area. Upgrade hint: In Nightmare mode, getting full Armor is difficult except with Mega-Health powerups. You can die and repeatedly get Mega-Healths; Toxic Sludge is convenient for dropping a single health point.
