The game shows off the differences between controlling the game’s protagonist and their partner, Poisonette. You can switch between the two at will, allowing you to accomplish different tasks.
The protagonist has an arm-mounted cannon, which can be used to shoot enemies. You’ll also have variable shot types, as the trailer shows them hurling a much slower projectile on top of the regular shots.
Meanwhile, Poisonette has no attacks per se, but can be used to remove corruption from the ground in the game’s stages. Unlike the Protagonist who moves rather slowly while shooting, Poisonette moves much faster, having to create loops to remove corruption.
That doesn’t mean Poisonette is defenseless, however. As shown in the trailer, enemies caught in one of her loops will also take damage from the purification.
Poison Control tells the story of the protagonist, who wakes up with Poisonette fighting over control of their body. The two must travel through the Belles Helles, where they must purify the souls of the fallen and defeat Kleshas, monsters born from dark emotions.
