Revenant/Doom 3

The Revenant in Doom 3 looks very reminiscent to it's original counterpart, taking the appearance of a tall, armored human skeleton with two rocket launchers mounted on each of it's shoulders.

This iteration has glowing green eyes and wears a thicker, more advanced red armor, consisting of tubes/wires along with the shoulder-mounted launchers. Their body below the collarbone is covered in a layer of almost transparent skin. This skin was originally a textural test in which id Software was trying to recreate an accurate skeleton by measuring it to the "flesh line". However, when they saw the creature in action with this test texture, they thought it looked interesting, and never removed it from the model.

The Revenant has baffled UAC scientists; it lacks visible internal organs and muscles, which doesn't explain the brute strength that the demon possesses. Presumably, unless every organic system is contained inside its metal shoulder plates, it must be completely controlled by the powers of Hell.

The Revenant makes its debut cutscene in the Monorail Skybridge: Facility Transport. It emerges from a dark corner of the area and fires a missile which destroys a huge steel column that sustains part of the ceiling, causing the column to fall and obstruct the Marine's path, forcing him to face the creature in search of another escape route.



Combat characteristics
The Doom 3 Revenant attacks in a very similar fashion as it's original counterpart. It fires rockets from it's shoulder mounted cannons at long range, and will resort to melee at close range.

However, it no longer maintains the same mobility as it did in the classic version, preferring to walk slowly instead of running very fast. They are much more aggressive and intelligent as a result, as they will quickly launch rockets from both of its shoulder-mounted cannons at once as it walks towards the player's position and occasionally sidestep to dodge the player's fire.

Revenants possess two types of melee attacks. The first melee consists of a basic clawing attack, which while limited in range and only does modest damage, can be executed pretty quickly. The second melee consists of a winded downward punching attack, reminiscent from the classic version, which while slower to execute, has further range than it's clawing and does more damage.

The Revenant's missiles are actually quite weak compared to the ones in Doom II. However, they are a lot harder to avoid, as they travel in rather confusing patterns, tending to wobble and spiral as though their guidance sensor isn't quite on the nose. To make up for this, the missiles can be now be destroyed while in flight, and Revenants do not appear to be immune from the damage caused by their own missile detonation.

Revenants are usually found alone, although they can occasionally come in pairs or be accompanied by other enemies such as Imps or Z-Sec soldiers.

Tactical analysis
The Revenant, despite its upgrades, can easily be taken out if the player has the right weapons and maintain good tactics to defeat it.

At close range, the Shotgun can be an effective weapon to take them out. If you're lucky, you can even kill the Revenant with a single blast aimed at its neck or the center of the clavicle. Most cases, however, it will take two blasts at blank range to completely take them out, so be aware as you dodge its melee attacks. First rush towards the monster with your Shotgun and fire at the Revenant at close range. This action will force it to claw you, so take good advantage of this to back off and take a second shot at the Revenant, which will kill it in the process. Resurrection of Evil and Lost Mission in the BFG Edition introduce the double-barreled shotgun, which will work wonders as it can easily kill the Revenant with one shot at point blank range.

At long range, the Plasma Gun is most effective against the Revenant thanks to its high rate of fire, and the plasma bursts "splash damage" can instantly neutralize the Revenant's missiles. If a Plasma Gun is not available, the Chaingun can also work well as the bullets can also destroy the Revenant's missiles. Keep in mind, however, as the Chaingun bullets lack the splash damage of the Plasma Gun, this could be a tricky procedure in destroying the Revenant's missiles. Other weapons such as the Machine Gun is also partially effective, although it takes some time and dodging. The BFG is not recommended because of the likelihood that the projectile will hit the Revenant's missile in flight, as well as the moderate threat the demon poses will make this weapon an unnecessary overkill.

Overall, the Revenant is considered a much less dangerous monster in comparison to it's classic counterpart. It moves a lot slower and does much less damage, as well as no longer appearing in large numbers. To make up for this, however, their attacks are a lot harder to avoid, as their rockets travel in erratic patterns, and have a medium reach with their melee attacks.

The general strategy when fighting against Revenants is to dodge behind cover when the missiles come close. This can allow the missiles harmlessly impact against an object used as a hideout. The homing missiles can also be dodged by sprint-strafing diagonally forward, although this takes some practice to perform and requires enough space to maneuver. Be very careful around flammable and explosive barrels (common in the Recycling sectors) as they can be detonated by both direct hits and splash damage from the missiles.

UAC Research Notes
These notes can be downloaded to the player's PDA during the course of the game:

Specimen 218 - Revenant

''This creature's endoskeleton is visible through a translucent non-solid skin. Despite the absence of any visible muscles, this creature is able to strike at close-range targets with enormous strength. Two shoulder-mounted cannons controlled by its nervous system allow this creature to fire guided rocket-propelled missiles.''

Trivia

 * In the E3 trailer of Doom 3 Alpha, the Revenant was shown to be acting like the old one: running at the player, then punching him.
 * The Revenant's shoulder missiles were originally going to drop missile ammo for you to pick up (and were also rumored to be actual weapons that the player could wield and guide the fired missiles), but for unknown reasons that concept was abandoned for the finished game.
 * Strangely, Revenants have 272 health; other monsters have an amount of health that is divisible by five.
