Crossbow is a bow that was available in Battle Royale. It was available in Rare and Epic variants. It uses Arrows as infinite ammo and has a headshot multiplier of 2.0x. It reloads every arrow, after each shot, like the Pump Shotgun. The weapon was introduced in Season 3, and it remained in the game till May 1st, 2018, when, with the release of Season 4, it got vaulted.
Surprisingly, on Patch 15.30 the Crossbow, together with the Cupid's Crossbow, got Reworked. Now dealing less damage but having a faster fire rate, while the headshot multiplier was decreased from 2.5x to 2.0x.
The Crossbow hasn't returned in the normal loot pool for almost 3 years, being the fourth longest vaulted item in game (the others being respectively the Zapatron, the Machine Pistol and Smoke Grenades).
The crossbow's arrows are slower and curved than sniper rifles bullets, so you have to predict better where the projectile will land, before shooting.
For this weapon, ammunitions aren't a problem, because arrows are infinite.
Of course for this advantage, it has some downsides. In fact it shoot and reload slower than other semiautomatic sniper rifles, and after every arrow, it has the reload animation of the next arrow, like the Pump Shotgun and Lever Action Rifle.
To bypass this last, you just have to switch to an another weapon and to re-switch to the crossbow. In fact thanks to this method you can do "Double-Crossbow".
Both rarities are able to eliminate a 150 shielded player in just 3 shoots, while for full shielded players, the Rare variant will need one extra shoot in order to eliminate him/her.
In headshot damages it will need, for both rarities, 2 shoots.
Due to loot settings not being updated to reflect the then-current patch, 50v50 V2 allowed access to the Crossbow for a short period of time despite it being Vaulted. The loot for 50v50 has since been updated.
