Petra’s defining feature is its double‑gun system. The salvo preparation time is extremely short at 1.5 seconds, the reload penalty after firing a salvo is almost negligible at 2 seconds, and the delay between shots from the two barrels is relatively brief. This gives you exceptional flexibility:
Fire salvos when the opportunity arises.
Or use single shots while still maintaining impressive burst damage over a short period.
In most other aspects, however, Petra looks average. Its mobility, with a top forward speed of 35 km/h and a reverse speed of 13 km/h, and its gun handling are rather mediocre, while its armor has a considerable number of weak spots.
