Characteristics
Edit
This weapon deals primarily 
Blast damage.
Advantages:
- Cannon Mode:
- Innate Blast damage – effective against Fossilized and Machinery.
- Launches cannonballs that explode in a 4 meter radius on impact with a surface or enemy, then splits into 6 smaller bomblets that rain down on the point of impact.
- Pinpoint accuracy.
- Heavy Caliber's accuracy penalty is minimal on this weapon.
- Innate
- Barrage Mode:
- High Puncture and good Impact damage in Barrage mode – effective against armor and shields.
- Fires a shotgun-like flak.
- Innate 1.6 meter Punch Through.
- High
- Good critical chance.
- High critical multiplier and status chance.
- Large ammo reserves.
- Reloads one cannonball at a time, which can be interrupted at any point, allowing for planned reloading.
- Reload time of 0.5 seconds for each cannonball, plus 0.75 seconds to begin/end reload.
- Innate polarity.
- Can use the launcher-exclusive Adhesive Blast mod.
- Can benefit from Firestorm, Amalgam Furax Body Count, and Cautious Shot.
Disadvantages:
- Cannon Mode:
- Innate Blast damage – less effective against Ferrite Armor and Infested Sinew.
- Explosion and bomblets inflicts self-stagger.
- Explosion and bomblets have linear damage falloff from 100% to 50% from central impact.
- Projectile has travel time with arcing.
- Innate
- Low overall status chance.
- Maximum range of 10 meters (affected by projectile flight speed mods).
- Very small magazine size.
- Draws ammo from the rare sniper ammo pool.
NotesEdit
- Reload time is 0.75s + 0.5s per round, coming to 2.25 total seconds to reload a completely empty mag.
- Each shot is loaded manually into the gun. Reload shows time required to fully load the gun, and is accordingly increased by mods like Magazine Warp. Reloading can be interrupted by firing the gun, being staggered or rolling, provided at least one shot is loaded.

- The Zarr can switch between two different firing modes using its Alternate Fire (default Mouse 3 ) button. These modes are officially named Cannon mode and Barrage mode;
- Cannon mode fires an explosive projectile in an arc that explodes on impact, dealing 175 Blast damage within a 4 meter radius, then splitting into 6 smaller projectiles that spread from point of impact and home in on targets, each dealing 50 Blast damage within a small radius.
- Barrage mode works in a shotgun-like pattern, shooting ten pellets in a wide spread, dealing physical damage, shoots faster than primary mode and has innate Punch Through of 1.6 meters. Pellets cover a maximum range of 10 meters (distance is affected by projectile flight speed).
- Multishot mods will increase the amount of bombs for Cannon shots, but each main projectile will always produce 6 cluster bombs. Multishot also increases the pellets of Barrage mode.
- The Zarr's current firing mode is indicated by orange text next to the Zarr's current Rank. Additionally, switching to Cannon mode is indicated by two short clicks, while switching to Barrage mode is indicated by three short clicks.
- The player should also take care in that the Zarr will always start in Cannon mode after Respawning, beginning a mission and switching to and from Archwing, resulting in the user possibly triggering self-stagger if used inside close quarters.
- Cannon mode fires an explosive projectile in an arc that explodes on impact, dealing 175
TipsEdit
- The Zarr is unique in the fact that it can quickly switch to a close range function that has no chance of staggering the player, allowing it to be used in tight spaces safely.
- While the Zarr has an average critical chance, its above average critical damage and bomblet behavior makes a crit build viable.
- The Zarr's individual reload mechanic is useful when reloading before the magazine is emptied as the reload will be shorter than the listed value. This is beneficial for situations where players need to fire a shot immediately, but cannot wait for the full reload to complete.
- Additional Punch Through will affect Cannon mode shots and the bomblets, allowing the primary shot to reach the center of a group of enemies before exploding rather than exploding on the first enemy and launching the cluster bombs back towards the shooter. This comes at the cost of not being able to hit flying enemies directly and the risk of shots passing through terrain, such as catwalks, and missing the intended target.
TriviaEdit
- The word "Zarr" could be a play on the Slavic word "Tsar", a word used as a title for supreme rulers of eastern and south-eastern European countries.
- In this context, 'Zarr' might be a reference to Tsar Cannon, one of the largest cannons in terms of caliber.
- It could also be a reference to Tsar Bomba, which was the most powerful nuclear weapon ever created.
- The Zarr is visually and somewhat functionally reminiscent of a swivel cannon.
- Upon release, the Codex entry misspelled "cannon" as "canon".
- When stuck to surfaces with Adhesive Blast, it has a unique sound effect signaling to the player that they are stuck.
- Adhesive Blast will cause the bombs to gain a 3 second timer before exploding. It does not change anything on the secondary fire
- The Zarr shares the same reload mechanic with the Strun, with the only difference that the latter shows the reload time of a single projectile.

Patch HistoryEdit
Reduced the following AoE weapons Radial Damage Falloff from central impact that were all previously 90%:
- Zarr: 50%
- Self Damage Changes
We are getting rid of Self Damage and replacing it with something else: instead of Self Damage, it’s now ‘Stagger’. This change completely removes the chance of killing yourself, and instead now creates scenarios where you will interrupt yourself - or ‘Stagger’ - to varying degrees if you aren’t careful.
The degrees of Self-Interrupt start with a small stumble all the way to full knockdown depending on how close you are to the center of explosion. Any Mods referring to Self Damage will be converted to acknowledge Stagger.
With this Self-Interrupt system, we have added dozens of new recovery animations that harness a ninja-like recovery experience. By pressing ‘Jump’ at the correct time, you can execute a ninja-skill-based knockdown recovery to ALL in-game knockdowns. This ninja recovery window is indicated by a glowing FX on your Warframe.
In the original Dev Workshop, we said:
As a result of this overall systemic change, Weapons with Stagger will be getting approximately a 20% buff in Damage, with any weapons with AOE receiving a 50% Radial Damage Falloff from central impact.
This is no longer accurate after continued testing. What we are doing now is:
No damage buffs have been added, but any weapons with AOE are receiving ~20% increase in Radius. Additionally, AOE weapons are receiving a 90% Radial Damage Falloff from central impact. This means on the very outer section of the explosion Radius 10% of the Damage will be dealt. Tactics will be deadly - aim true, Tenno.
Why: Several players brought up the history of the Tonkor and we want to make sure we ship this change in a place that’s conservative in its starting point from a balance perspective. The complete removal of Self Damage does change the pace of destruction with some of the game’s most powerful weapons, so we want to make sure we can iterate upwardly instead of releasing a bonanza of explosions with no other choices.
- Greater than 100% Status having meaning
Shotguns have a unique Role here based on a very patch-work history with how they interact with Status Chance. A Shotgun that shoots 99% Status Chance would give you 35% (roughly) status per pellet. 100% Status Gives you 100% Status per pellet. This huge jump in performance happens with just a 1% gain - why? Well, to answer that we have to look at our choice to make what the UI conveys reality. It would feel broken to shoot a Shotgun with 100% Status and not see a perfect spread of Effects. In reality, to make Status consistent we have to treat Shotguns as a special case.
Shotguns as a special case means we have buffed the Status Chance of all Shotguns by x3 or greater. The UI now behaves to show the reality that you are determining Status Chance per pellet.
