Retro Gatling is an alternate for the Peashooter's Pea Gatling ability. It can only be obtained by sticker packs. Once it is obtained, it can be equipped in place of Pea Gatling in the character customization menu. It takes 30 seconds to recharge.
Retro Pea Gatling uses the ancient Peashooter techniques of manually cranking out peas. Although it has a slower rate of fire, the peas are ancient and far more damaging.
The difference between the two is that the Retro Gatling has a slower rate of fire and only half as much ammo as the Pea Gatling, and the peas have a lower velocity and a quicker damage falloff. In exchange, each pea deals 8 to 12 impact damage and 9 to 14 critical damage, significantly higher than the standard Pea Gatling's.
Contrary to popular beliefs, the recoil between Retro Gatling and Pea Gatling are not actually very different: Both veer significantly to the right at a 30 degrees angle upwards, and Retro Gatling's climb rate is only slightly slower compared to Pea Gatling. Despite this however due to less ammo and a slower fire rate, Retro Gatling becomes more accurate than Pea Gatling, as, it veers slower and not as much. The player may compensate for this by dragging their aim to the left at a 30 degrees angle downward; this can eliminate the need to fire Retro Gatling in bursts, as aimed shots should be able to hit the target reliably even at full auto.
The Retro Gatling sacrifices ammo and firing speed for more damage for each hit. Overall, the Retro Gatling will deal less damage per second, and the player will also have more accuracy with the ability.
- The helmet that the Peashooter wears while using this ability slightly resembles a German Pickelhaube, the same helmet worn when a Repeater in Plants vs. Zombies 2 is fed Plant Food.
- The firing barrel that visibles in the Peashooter's "mouth" resembles an actual Gatling gun.
- On the firing barrel's left side, there is a crank, yet the Peashooter never operates it despite the Stickerbook description claiming otherwise.
- It regains the damage reduction to it from Pea Gatling.
