The Supra is a heavy laser gun with a short wind up time.
The Supra is a tri-barrel laser repeater of Corpus design that is unlockable through Energy Lab Research in the Dojo. It can be seen in the hands of Corpus Techs throughout Corpus-controlled regions, and is effectively the Corpus equivalent of the Gorgon.
Supra has a decent fire rate like the Gorgon, but it is less accurate at longer distances. Firing in short bursts may help improve accuracy.
Alternatively, use the mod Stabilizer to almost completely eliminate the Supra's high recoil, and make it more comfortable to fire overall.
The Supra's shot travel time can be exploited to create a 'blanket' or 'curtain' of projectiles down longer approaches, effectively forcing enemies to take damage if they try to advance through the projectile cloud.
Piercing Hit makes this gun even more augmented versus Grineer because of their weakness to Puncture damage, the Supra's strongest stat.
Shred or Metal Auger can help hit more enemies, somewhat balancing the high ammo consumption.
Mods that increase fire rate, as well as provide good burst damage, are needed in order to take down heavier units faster.
You can also use the Supra as a normal assault rifle, firing in bursts of 2-3 shots at a time. This way you save a lot of ammo because you aim at individual targets instead of a whole group. "Spraying & Praying" eats up your ammo in less than a minute, so be careful.
Cancelling the reload animation on its third-quarter period counts as a reload, but this may not benefit as much in comparison to the Soma.
With the Entropy Burst equipped, It will increase the total status chance to 22.5%, which is very high for a heavy machine gun. Note that any mods that increase status chance (such as Malignant Force, only adds status based on the weapons original status chance, and not the new base status chance given by Entropy Burst. With all 4 dual stat mods and Split Chamber, the Supra can achieve a 47.1% status.
