Capable of firing multiple rockets at once, the Angstrum is a handheld instrument of destruction.
The Angstrum is a heavy pistol of Corpus design that fires tiny but powerful rockets. Its charge-based trigger allows for firing precise single shots, or emptying the entire magazine as a spread barrage for engaging single heavy targets or large groups. It was released in Update 13.3.
Use Magnum Force if you wish to cover a greater area (as there is no secondary counterpart for Firestorm), as the damage bonus granted by this mod can help counteract any loss of damage due to the accuracy penalty. Bear in mind this is at the expense of the Angstrum's charged shots at long range.
Increasing the magazine size will result in a higher projectile count when firing a totally charged shot. Bear in mind that increasing the magazine size will also increase the time it takes to charge the shot.
Combining the magazine build with Barrel Diffusion and/or Lethal Torrent will yield the chance of a totally charged shot firing 21 projectiles.
With the above primed mod, it can reach 24.
Using the previous combination with Mirage's Hall of Mirrors can yield a total of 105 projectiles in one salvo. This is obviously not recommended for low configs.
Can reach 120 if chances play out.
Gunslinger and/or Lethal Torrent speeds up the charge time, allowing for faster firing rates. This is especially important if one is maximizing magazine capacity, as the charge time for a large magazine can be long.
Mag's Bullet Attractor synergizes well with this weapon, as it allows all the rockets fired to be redirected unto a single target, dealing massive amounts of damage. This is most useful against heavy units like Napalms, and against bosses that have no weak spots like Ambulas.
It is highly recommended to equip a Pistol Ammo Mutation mod to remove practically all ammunition problems.
Lethal Momentum can increase rocket velocity by up to 40%, significantly reducing the amount of lead time required for distant targets.
The innate polarity can somewhat limit elemental modding potential, thus making it a less desirable polarity for elemental modding. If you wish to focus more on elemental damage, then it is recommended to either ignore the polarity or use Forma to turn it into a more suitable polarity.
Putting Deep Freeze and making use of the secondary elemental damages that use Cold damage can make use of this polarity.
Tapping the fire button will let out a single, very accurate rocket which can be used to pick off targets from long or medium range; or be held halfway or fully to release half or the entire magazine respectively, which will cause a wide spread of rockets to cover large groups at closer ranges.
The Angstrum must reach a given level of charge in order to fire a single shot or volley. Use Fire Rate mods such as Gunslinger to reduce the time required to charge.
Use the reload button to cancel charge to avoid unwanted shots.
Keep in mind that Multishot will eliminate the dead-on accuracy of the single shot, as it will cause 2 or 3 rockets to skew outwards, with none of the rockets going right where the reticle is.
The Angstrum's charge cannot be held. The weapon fires as soon as it is fully charged.
Constantly tapping the fire button will not cause this weapon to stall like the Ogris. If you accidentally begin charging the weapon, without meaning to, you can stop the shot simply by spamming your charge button and hitting reload while you prevent the weapon from releasing a rocket.
There is a delay between pressing the fire button, and the rocket actually being ejected. pressing the fire button again before it is ejected will cancel the ejection-jamming like the Ogris.
Unlike a shotgun which shoots a completely random spread, the Angstrum is shown to form a geometrical structure (depending on the grenade quantity) of:
One - A single accurate shot.
Two - Two separate horizontal shots.
Three - A triangle.
Four - Diagonal square.
Five - Pentagon.
Six - Hexagon.
Seven - Hexagon with a center point.
Eight - Pentagon with a center triangle.
Nine - Hexagon with a center triangle.
Unlike other explosive weapons in the game, the Angstrum does not have two damage instances: the impact with the enemy and the AoE explosion. Instead, the rockets simply explode and deal only AoE damage.
This means that any elemental damage is also dealt in an AoE.
The AoE blast has a very high falloff, making direct hits essential.
Angstrum's shots bounce off Nullifiers' barriers rather than exploding, and will detonate upon hitting another solid object. Beware as this includes the player who fired it.
When using Ivara's ability Navigator on the Angstrum's rockets, they travel extremely slow, rendering them effectively useless.
Firing Angstrum first and then activating Navigator works normally.
The Angstrum's name is derived from Angstrom, which is a unit of measurement that is roughly 0.1 nanometers in length.
This weapon appears to be of Corpus design, making it their second explosive weapon following the Penta.
When charging, the rockets in the chamber lower into the gun itself.
The Angstrum's concept of a conventional-appearing weapon (pistol in this case) firing rockets is similar to that of the Gyrojet from the 1960s.
Its boxy design is similar to the IMI Uzi MP-2 machine pistol, including the way the weapon can be held.
