Repeater is a peashooting plant appearing in Plants vs. Zombies as well as their Chinese spin-offs. He costs 200 sun, and fires two peas at the same rate as a normal Peashooter.
Repeater is obtained after beating Level 1-8, and is the last non-mushroom plant received in the Day stage. He can be upgraded to the Gatling Pea for 250 sun upon purchasing from Crazy Dave’s Twiddydinkies for $5000.
In Beghouled and Beghouled Twist, Repeater acts as Peashooter‘s upgrade, costing 1000 sun. A reverse version of Repeater appears in the Vasebreaker mode starting with To the Left, functioning identically to Split Pea’s back head.
Overall, Repeater could be considered as two Peashooters combined into a single plant, with double the firepower and sun cost of the average Peashooter, and the benefit of space conservation, costing less than 2 Peashooters, and a faster recharge rate. This means that while the player will have more difficulty deploying Repeater early, the plant itself will prove to be much more useful as the level progresses. This is further improved by the fact that Gatling Pea, Repeater’s upgrade, is capable of the highest damage per second potential in the game under the right condition. However, Repeater continues to suffer from some of Peashooter‘s weaknesses, namely poor crowd control capability and the inability to bypass Screen Door Zombie and Ladder Zombie’s shields.
Like other pea-firing plants, Repeater benefits greatly from the use of Torchwood, as the latter can ignite peas passing through it, doubling their damage and giving them small splash damage. The player should remember however, that flaming peas can remove ice-based effect from their direct target, making plants like Ice-shroom less effective, but not their splash damage targets.
In Vasebreaker, Repeater is unique in that it will only appear as a backward facing variant, just like the back head of a Split Pea. Therefore, it should be planted to the right, instead of to the left side of the levels. Backward Repeater is particularly useful against fighting vase Gargantuars, as it can avoid being in their course and can shoot them with relative safety.
However, one should always be careful; since the Repeater is firing backwards, it’s actually firing its peas slower at the zombies, since its peas are not going against the zombies and in the opposing direction, but instead goes along with them in the same direction. Because of this, one should always use caution when using the reverse Repeaters.
