Lilly was seen holding a pistol on the thumbnail for Mad Hunger Games.
Lilly is similar to, and is inferior to Jack.
She has better hp recovery at higher health, and a faster fire rate, but has less hp, recovers less hp when at lower health, deals less damage with each shot and has less dps, quickly empties her clip, and reloads much slower. On top of that her upgrades are less effective than Jack; who has better damage range, and later on, better accuracy as well. Overall is less powerful, with only few different upsides that don't do much better, and Jack beats her with many more upsides, which makes Lilly like a beginner Jack that's only worth using when the player has not gotten him.
Also very similar to Duke, and Dennis, but overall Lilly still isn't that great.
Her walkspeed was nerfed from 11 to 10 during the character stats update.
Her fire rate was also nerfed, decreased from 20 Shots/s to 18 Shots/s.
