Walker is a crit-scaling shotgunner whose kit snowballs through sustained combat. Every critical strike permanently increases his crit amplification, rewarding extended fights. His ultimate fires a shotgun blast with spreading pellets and enters a powered-up mode where normal attacks gain area damage, bonus crit chance, and stronger pellets — and each critical strike during this window extends its duration. His revolver finisher targets the lowest-health enemies, executing wounded targets and granting him a shield on kills. The shotgun melee smack stuns and knocks enemies down, then shoots them on the ground for heavy follow-up damage while cutting their damage output. When his health drops low, his crit rate spikes further, and missed crits still build toward his crit rating, ensuring the scaling never stalls. During his ultimate, he gains control immunity and life leech.
