The XPMl21 Rocket Launcher, or just Rocket Launcher in Serious Sam Advance, is a rocket launcher that fires slow rockets at a decent rate of fire without having to be reloaded.

OverviewEdit

The XPML21 is an experimental rocket launcher designed to provide infantry forces with a fast firing rate of anti-armor rockets. The weapon has an advanced loading mechanism that is capable of firing up to 85 missiles a minute.

The rocket launcher fires a rocket every time the fire key is pressed. Rockets will continue to be fired if the player holds down the fire key. When the fire key is held down, the rocket launcher has a high rate of fire. Rockets fired by the rocket launcher will go straight until they hit something. They are quite slow however, and cannot lock onto targets.

In Serious Sam Advance, the rocket launcher fires chemically powered rockets. The rockets themselves can deal a lot of damage if they hit a target, and the explosion it makes can harm any enemy near the impact site, even if the rocket hits an enemy. It has a fairly high rate of fire and its projectiles are somewhat fast, which allows the user to quickly bombard a target with multiple rockets.

In Serious Sam 3: BFE, the rocket launcher has a much different design and new firing sounds. The firing and loading mechanism has also changed, but still retains the same fire rate from the previous games.

OccurrenceEdit

In Serious Sam: The First Encounter, the rocket launcher first appears in Valley of the Kings, but can be obtained earlier in Temple of Hatshepsut as a secret, along with rockets. In Serious Sam: The Second Encounter, there are 3 rocket launchers that appear in Sierra de Chiapas, two of which can be found as secrets. In then appears on the first or second levels in the other eras.

In Serious Sam 3: BFE, the XPML21 is first obtained in No Place to Hide, either normally or via secrets. It is used at this point to take down the pursuing Technopolip that initially appears in this level. In Serious Sam Fusion 2017, the rocket launcher can be found in a room in Summer in Cairo in the same building where the player obtains the sledgehammer. The player needs to find a secret key to unlock the door before they can get the rocket launcher.

In Serious Sam Advance, the rocket launcher is first obtained in Slave Quarters.

TacticsEdit

Serious Sam 1Edit

  • The rocket launcher is very useful against strong enemies, such as Arachnoids and Major Bio-mechanoids; it usually takes around five or so rockets to kill them (two for juvenile Arachnoids), and because it has a fairly fast rate of fire, getting that amount of rockets into the air quickly is easy.
  • Groups of weak enemies, such as the Beheaded Rocketeer, can easily be destroyed with this weapon. A rocket that targets the center of the group usually does the most damage because the splash damage from the rocket hits everybody around the victim, which is usually the rest of the group.
  • The rocket's slow speed makes it impractical to use at long range. However, if a target is too far away for a charged MK III Grenade Launcher shot to reach it, a volley of rockets will work, but it will take some time for the rockets to reach their destination.
  • The rocket launcher is not recommended against fast enemies that move left and right often, such as zig-zagging Kleers. The rocket's rather slow speed makes it very possible for the fast enemy to go past the rocket before it hits.
  • This weapon can be dangerous to use against enemies that try to get close to the player, such as Beheaded Kamikazes or Marsh Hoppers, if the player isn't careful. If an enemy gets close to the player while the player is firing or just after a rocket has been fired, the player will suffer significant damage because of the splash damage from the rocket. The resulting explosion from the Kamikaze plus the damage from the rocket can severely deplete the player's health and/or armor.

Serious Sam 3: BFEEdit

  • The rocket launcher is useful for clearing out groups of weak enemies quickly, such as hordes of Kleer Skeletons and Hatchling Antaresian Spiders. The explosion radius damage can kill multiple weak enemies in one shot. To maximize its effect, a rocket should be aimed at an enemy towards the middle of the group if possible. The explosion from the rocket hitting the enemy will hit all of his buddies around him, doing more damage than a rocket to the first enemy in the group would do.
  • It is also handy against larger enemies, such as the Adult Arachnoid and Scrapjack. It does enough damage that it can kill them after a few hits, and its decent rate of fire and, as these enemies don't usually strafe, (with the exception of Adult Arachnoids) this ensures that it'll consistently hit enemies at any range.
  • The rocket launcher is an ideal weapon against Hatchling Arachnoids; one rocket will instantly destroy it, making it a good choice for clearing out groups of them.
  • It is a good jack-of-all-trades weapon later in the game. It does a high amount of damage per shot (especially if the rocket makes a direct impact), has a good rate of fire, and most importantly, its ammo is common thanks to Ammo Crates. These make it very effective against any enemy the game throws at the player in the last few levels.
  • It is the "weakest" out of all the weapons that can damage certain bosses, such as the Technopolip or the Khnum. It has a slower projectile speed than the AS-24 Devastator and does less damage than the C-4 Demolition Charge. However, it has a consistent rate of fire, which lets the player constantly damage the enemy without needing to be reloaded.

Serious Sam AdvanceEdit

  • The rocket launcher is a great weapon against stronger enemies, such as the Cyclops or the Gunrilla. Two to three shots are needed to take out anything but a boss. This makes it very useful later in the game, where strong enemies make up most of the opposition the player faces.
  • It also works very well against groups of enemies. One rocket can harm multiple enemies thanks to it's explosion. A few rockets can completely clear out a group of enemies. The Rocket Launcher's firing speed allows the player to fire off multiple rockets quickly, which lets them clear out a group of enemies even faster than the minigun if the enemies are right next to each other.
  • The explosion from a rocket can kill enemies even if the player doesn't see them. This is useful for killing enemies around corners or when the player's health is low and they need to avoid direct confrontations with enemies.
  • One downside with the rocket launcher is that, if it hits an enemy projectile, it will explode. Therefore, the player should try to time it so that a rocket is fired between an enemy's attack. This is more useful against groups of enemies because of the amount of projectiles fired by a group.
  • Don't use the launcher if an enemy is close. A rocket's explosion will do a good amount of target to the player if they're close to a rocket explosion if the target.

Behind the scenesEdit

  • In Test 1 and beta screenshots, the rocket launcher had a completely different model (as seen in the gallery).

TriviaEdit

  • In Serious Sam 3 BFE, the rocket launcher causes knockback at certain angles, even on Tourist difficulty where no damage or knockback is normally expected. This can be exploited to make long-range jumps (for speedruns). This is fixed in Serious Sam Fusion 2017.
