The '''doomsday rocket launcher''' is a single-use, single-shot rocket launcher that is one of the strongest weapons in the game, along with the [[triple rocket launcher]].

== Acquisition ==
Doomsday rocket launchers cannot be crafted, and must be either acquired through [[trade]], as a [[quest]] reward, found in [[ancient shrine]]s, or looted from [[Raiders]], specifically from Heavy Mercenaries in [[Outlanders|Outlander]] and [[Pirates|Pirate]] raids. In the last case, care must be taken to kill or down the raider before they can fire the weapon.

<!-- Raider is linked instead of a faction because its a Mercenary used by both Outlanders and Pirates-->

== Summary ==
The doomsday rocket launcher is a single-use consumable, unlike most weapons. Once fired once, the launcher disappears completely. It cannot be reloaded, nor can any resources be salvaged from it. When fired, the cooldown time of the weapon is still observed. It is similar to a [[triple rocket launcher]] in this respect. It's worth noting that this launcher is never automatically aimed by [[colonist]]s - they have to be ordered to fire by the player.

When fired, the doomsday rocket launcher fires a rocket that produces a single explosion in a 7.8 tile radius explosion, dealing 50 [[Damage Type#Bomb|bomb damage]]. Afterwards, 3 smaller explosions deal 10 [[Damage Type#Flame|flame damage]], potentially igniting targets, and covering the ground in [[Filth|chemfuel puddles]] which also then ignite. These secondary explosions can exceed the displayed blast radius of the rocket so care must be taken when firing. There are some unconfirmed reports that the secondary explosions can also detonate behind walls.{{Check Tag|Confirm}}

If it is damaged in item form, i.e. not held by a pawn, by [[Damage Type#Flame|Flame damage]], it may explode.{{Check Tag|Detail needed}} The launcher will spark and emit a hissing sound shortly before exploding some time later. The explosion deals 50 Bomb damage in a 7.8 tile radius around itself.

== Analysis ==
The doomsday rocket launcher is a single use, but extraordinarily effective solution to human raids of all kinds. It combines significant damage, large area of effect, incendiaries, and long range. This allows it to quickly devastate, if not outright end, human raids that show up. As they are very difficult to acquire in bulk, rocket launchers are best as emergency weapons.

Doomsday rocket launchers have a range that dwarfs most other weapons; being tied with the triple rocket launcher and only surpassed by the [[sniper rifle]]. Therefore, they are perhaps the ultimate solution to dispatch of dangerous sieges and late-game tribal raids. Raiders that "prepare" can be handled with multiple [[mortar]]s, or in the case of tribals, even just a [[sniper rifle]].

[[Mechanoids]] are immune to both [[Damage Type#Flame|flame damage]] and to being ignited. This significantly reduces the effectiveness of Doomsdays. As [[centipede]]s (and to a lesser extent, [[termite]]s) have such high health scales, doomsday rocket launchers aren't the raid-ending threat like they are against humanoids, but they still deal decent damage.

=== Compared to triple rocket launchers ===
[[Triple rocket launcher]]s fire 3 rockets; each rocket deals 50 bomb damage, the same as the doomsday's main explosion, but with a smaller radius. Even one rocket is easily enough to kill humanoids. Therefore, multiple rockets (which may overlap) are more effective against bulkier [[mechanoid]] targets, like [[centipede]]s. However, the triple rocket launcher doesn't have the pure raid-ending potential that the doomsday launcher has - it is less effective in its niche than the doomsday launcher is at its niche.

There also exists opportunity cost - you may want to "save" doomsday launchers against devastating raids, but this may not always be possible. But you may only have triple or doomsday rocket launchers available, so don't be picky about either one.

=== Fighting against ===
As expected, doomsday rocket launchers in the hands of raiders are incredibly dangerous, and should be made priority targets. You can either focus firing on them, or by getting them to waste their single shot on an inconsequential or difficult to hit target.

[[Psychic shock lance]]s and [[psychic insanity lance]]s have a comparable range (1 tile shorter) and fire much faster (0.5s warmup vs 4.5s warmup), which will make the target a nonthreat. [[Psycast]]s{{RoyaltyIcon}} can also [[berserk]] the pawn in question for the same effect.

=== Wealth management ===
Doomsday rockets are very effective form of [[wealth management]]. Items are almost always bought at a market value loss, and when actually used, the entire {{icon Small|silver||1000}} value is consumed. The rocket itself is a fairly strong last ditch weapon.

=== Doomdropping strategy ===
Combining a doomsday-armed pawn with a [[transport pod]] allows the player to rapidly position an effective counter to most raids anywhere on the map, even on larger map sizes. The pawn need not carry the doomsday day-to-day, and instead a [[shelf]] or stockpile an be placed next to the transport pods to allow a pawn to quickly switch from their current weapon to the doomsday before launching.

Pawns are exposed both before firing, and after firing if the launcher fails to break the raid. High quality armour is recommended, but high [[move speed]] is more useful. [[Go-juice]] is very useful, boosting speed and prevents [[pain]] downing your pawn.

If the [[Royalty DLC]]{{RoyaltyIcon}} is active, there are more options to ease escape. [[Jump pack]]s{{RoyaltyIcon}} or [[locust armor]]{{RoyaltyIcon}} make reposition faster, the Invisibility [[psycast]] renders the pawn immune to counter-fire before launching, and the Skip psycast can move a pawn.
