Tips[]
- With a large portion (80%) of its total damage relying on Puncture, it is somewhat more viable to equip Piercing Hit and/or Piercing Caliber than with most weapons.
- Similarly, because the Tetra has no Slash Damage, Sawtooth Clip and Fanged Fusillade are completely useless.
- Similarly, because the Tetra has no
- With its high recoil, Stabilizer is a good choice to make this weapon more useful at longer ranges.
- While the Tetra has less accuracy than the Dera and weaker overall firepower than the Supra, it deals more damage than the former and has better handling than the latter, making it a good middle-ground weapon in terms of performance. It is also the only Corpus Primary energy weapon whose blueprint can be purchased off the Market, making it more accessible than the clan tech Dera and Supra.
- Third lowest fire rate of all fully automatic rifles, after Buzlok and Panthera.
Trivia[]
- True to the Tetra's description, the word "Tetra" is a Greek prefix meaning "four"
- The Tetra's battery-like magazines are attached in front of its barrel
- Each of the four "batteries" composes one-fourth of the gun's entire magazine size. Firing up to each quarter (15 rounds by default) round will cause a "battery" to eject.
- All remaining "batteries" will be ejected when reloading manually. The reload animation consists of pushing the stock in, removing the muzzle, and replacing it with a new muzzle complete with fresh batteries before pulling the stock back into place.
- It appears to fire from four distinct barrels, in a clockwise motion, starting at the top right barrel and ending at the top left.
