Infection Gunfight

Infection Gunfight is an asymmetric Humans vs. Zombies FPS game on Roblox by 9thD Workshop, released in mid-2024. With 112 million visits, 404K+ favorites, and 400-700 concurrent players, it is one of the fastest-growing shooter games on the platform - reaching 100 million visits within roughly 18 months of launch. It is available on desktop, mobile, tablet, Xbox, and PlayStation.

Each 16-player round begins with players assigned to the human or zombie side. The tension escalates mid-round: when a zombie touches a human, that human converts and joins the zombie team, growing the horde. Humans must survive the timer or eliminate every zombie before being overwhelmed:

• ⚔️ Asymmetric round-based combat - humans defend, zombies infect
• ⚔️ Snowball dynamic - each infection grows the zombie horde mid-round
• 💎 Gems and Credits currency system for unlocking weapons, skins, and zombie variants
• 💎 Luxury Cases (loot boxes) containing weapons and skins at varying rarities
• 🏆 Ranked progression with a competitive leaderboard
• ⚔️ PVE Mode - a separate co-op mode for playing against AI zombies

Weapons range from pistols and SMGs to rifles and special items like the Minigun. Skins cosmetically upgrade both weapons and zombie characters. Roblox Premium subscribers receive a Credits and XP Boost, accelerating both cosmetic and rank progression. The game also runs a separate Social Rewards system tied to social media engagement.

Infection Gunfight shares audience with Roblox FPS titles like Arsenal and Bad Business but carves its niche through the zombie infection mechanic and generous ongoing reward drops.
